APPLICATIONS INFORMATION
3.3
Rail-to-Rail Output
The MCP6141/2/3/4 family of operational amplifiers
are fabricated on Microchip’s state-of-the-art CMOS
process. They are stable for noise gain of 10 V/V or
higher. Microchip also produces a unity gain stable
product, the MCP6041/2/3/4 family, which has similar
specifications. The MCP6041/2/3/4 family has a bandwidth of 1.4 kHz at a noise gain of 10 V/V, while the
MCP6141/2/3/4 family has a bandwidth of 10 kHz at a
noise gain of 10 V/V. These devices are suitable for a
wide range of applications requiring very low power
consumption. With these op amps, the power supply
pin needs to be bypassed with a 0.1 µF capacitor.
The MCP6141/2/3/4 family Maximum Output Voltage
Swing defines the maximum swing possible under a
particular output load. According to the specification
table, the output can reach up to 10 mV of either supply
rail with a 50 kΩ load.
3.1
The maximum operating VCM that can be applied to the
inputs is VSS -0.3V and VDD + 0.3V. Voltage on the
input that exceeds this absolute maximum rating can
cause excessive current to flow in or out of the input
pins. Current beyond ±2 mA can cause possible reliability problems. Applications that exceed this rating
must be externally limited with an input resistor, as
shown in Figure 3-1.
Rail-to-Rail Input
The input stage of these devices uses two differential
input stages in parallel; one operates at low VCM (common mode input voltage) and the other at high V CM.
With this topology, the MCP6141/2/3/4 family operates
with VCM up to 300 mV past either supply rail. The Input
Offset Voltage is measured at both VCM = VSS - 0.3V
and VDD + 0.3V to ensure proper operation.
3.2
3.4
Input Voltage and Phase Reversal
The MCP6141/2/3/4 op amp family uses CMOS transistors at the input. It is designed to prevent phase
reversal when the input pins exceed the supply voltages. Figure 2-33 shows an input voltage exceeding
both supplies without output phase reversal.
Output Loads and Battery Life
The MCP6141/2/3/4 op amp family has low quiescent
current, which supports battery-powered applications.
There is minimal quiescent current glitch when chip
select (CS) is raised or lowered. This prevents excessive current draw and reduced battery life when the
part is turned off or on.
Heavy resistive loads at the output can cause excessive battery drain. Driving a DC voltage of 2.5V across
a 100 kΩ load resistor will cause the supply current to
increase by 25 µA, depleting the battery 43 times as
fast as IQ (0.6 µA typ) alone.
High frequency signals (fast edge rate) across capacitive loads will also significantly increase supply current.
For instance, a 0.1 µF capacitor at the output presents
an AC impedance of 15.9 kΩ (1/2πfC) to a 100 Hz
sinewave. It can be shown that the average power
drawn from the battery by a 5.0 Vp-p sinewave
(1.77 Vrms) under these conditions is:
EQUATION
P SUPPLY = ( V DD – V SS ) ( I Q + V L ( p – p ) fC L )
= ( 5V ) ( 0.6µA + 5.0V p – p ⋅ 100Hz ⋅ 0.1µF )
= 3.0µW + 50µW
This will drain the battery 18 times as fast as IQ alone.

Stability
The MCP6141/2/3/4 op amp family is designed to give
high bandwidth and faster slew rate for circuits with
high noise (Gn) or signal gain. The related unity-gain
stable MCP6041/2/3/4 op amp family has lower AC
performance, but it is preferable for low noise gain
applications.
Noise gain is defined to be the gain from a voltage
source at the non-inverting input to the output when all
other voltage sources are zeroed (shorted out). Noise
gain is independent of signal gain and depends only on
components in the feedback loop.

noise gain should meet the specified requirement:
3.6
Capacitive Load and Stability
Driving capacitive loads can cause stability problems
with voltage feedback op amps. Figure 2-21 shows how
increasing the load capacitance will decrease the phase
margin. While a phase margin above 60° is ideal, 45° is
on the verge of instability. As can be seen, up to
CL = 150 pF can be placed on the MCP6141/2/3/4 op
amp outputs without any problems, while 250 pF creates a 45° phase margin.
When the op amp is required to drive large capacitive
loads (CL >150 pF), a small series resistor (RISO in
Figure 3-4) at the output of the amplifier improves the
phase margin. This resistor makes the output load
resistive at higher frequencies, which improves the
phase margin. The bandwidth reduction caused by the
capacitive load, however, is not changed. To select
RISO, start with 1 kΩ, then use the MCP6141 SPICE
macro model and bench testing to adjust RISO until
there is a minimum frequency response peaking.

Option
The MCP6143 is a single amplifier with a chip select
(CS) option. When CS is pulled high, the supply current
drops to 20 pA (typ.) and goes through the CS pin to
VSS. When this happens, the amplifier is put into a high
impedance state. By pulling CS low, the amplifier is
enabled. If the CS pin is left floating, the amplifier will
not operate properly. Figure 3-5 shows the output
voltage and supply current response to a CS pulse.

Layout Considerations
Good PC board layout techniques will help you achieve
the performance shown in the specifications and typical
performance curves. It will also assist in minimizing
Electro-Magnetic Compatibility (EMC) issues.
3.8.1
SURFACE LEAKAGE
In applications where low input bias current is critical,
PC board surface leakage effects and signal coupling
from trace to trace need to be considered.
Surface leakage is caused by a difference in voltage
between traces, combined with high humidity, dust or
other contamination on the board. Under low humidity
conditions, a typical resistance between nearby traces
is 1012Ω. A 5V difference would cause 5 pA of current
to flow, which is greater than the input current of the
MCP6141/2/3/4 family at 25°C (1 pA, typ).
The simplest technique to reduce surface leakage is
using a guard ring around sensitive pins (or traces).
The guard ring is biased at the same voltage as the
sensitive pin or trace. Figure 3-6 shows an example of
a typical layout.

FIGURE 3-7:
Two possible guard ring
connection strategies to reduce surface leakage

3.8.2
COMPONENT PLACEMENT
In order to help prevent crosstalk:
• Separate digital components from analog components, and low speed devices from high speed
devices.
• Keep sensitive traces short and straight. Separate
them from interfering components and traces.
This is especially important for high frequency
(low rise time) signals.
• Use a 0.1 µF supply bypass capacitor within 0.1”
(2.5 mm) of the VDD pin. It must connect directly
to the ground plane.

SIGNAL COUPLING
The input pins of the MCP6141/2/3/4 family of op amps
are high impedance, which allows noise injection. This
noise can be capacitively or magnetically coupled. In
either case, using a ground plane helps reduce noise
injection.
When noise is coupled capacitively, the ground plane
provides shunt capacitance to ground for high frequency signals (Figure 3-8 shows the equivalent circuit). The coupled current, IM, produces a lower voltage
(VTRACE 2) on the victim trace when the trace to ground
plane capacitance (C SH2) is large and the terminating
resistor (RT2) is small. Increasing the distance between
traces and using wider traces also helps.

Typical Applications
3.9.1
BATTERY CURRENT SENSING
The MCP6141/2/3/4 op amps’ Common Mode Input
Range, which goes 300 mV beyond both supply rails,
supports their use in high side and low side battery
current sensing applications. The very low quiescent
current (0.6 µA, typ.) help prolong battery life, while the
rail-to-rail output allows you to detect low currents.
Figure 3-9 shows a high side battery current sensor circuit. The feedback and input resistors are sized to minimize power losses. The battery current (IDD) through
the 1 kΩ resistor causes its top terminal to be more
negative than the bottom terminal. This keeps the common mode input voltage of the op amp ≤ VDD, which is
within its allowed range. The output of the op amp can
reach VDD - 0.1 mV (see Figure 2-26), which is a
smaller error than the offset voltage.
RT2
VDD
FIGURE 3-8:
Equivalent circuit for
capacitive coupling between traces on a PC
board (with ground plane).
When noise is coupled magnetically, the ground plane
reduces the mutual inductance between traces. This
occurs because the ground return current at high frequencies will follow a path directly beneath the signal
trace. Increasing the separation between traces makes
a significant difference. Changing the direction of one
of the traces can also reduce magnetic coupling.
If these techniques are not enough, it may help to place
guard traces next to the victim trace. They should be on
both sides of the victim trace and be as close as possible. Connect the guard traces to ground plane at both
ends and in the middle for long traces.
