EVM Components
4.1
Power
Power is applied to the device with test points VCC and VEE at TP1 and TP3, respectively. These test
points power both the socketed diff-amp and the onboard reference amplifier. The board is initially
populated with an OPA207 as the reference amplifier, but if a different device is used then take care that
the new device can operate with the same supply as the diff-amp.
4.2
Inputs
Inputs are applied to the device using test points VIN+ and VIN-. Alternately, they can be applied at
banana jacks J3 and J5. This is recommended if high currents will flow through the input. The jacks are
spaced a 1/4 inch apart to interface with standard connectors. Two footprints are provided at the input for
shunt resistors if it is desired to test an amplifier for a current sense application. Additionally, footprints are
provided for edge mount SMA connectors for easily interfacing with other EVMs or test equipment.
4.3
Output
The output of the circuit may be accessed through test point VO or by adding an SMA connector at J23.
4.3.1
Output Filtering
RO and CO provide the ability to apply a single-pole RC output filter. Care must be taken not to overload
the output with excess capacitance, as this could lead to stability issues. The cutoff frequency of the
output filter is calculated as shown in Equation 1:
1
fc-o =
2S u RO u CO
(1)
4.4
Reference
There are multiple methods of applying a reference voltage to the device. The reference voltage is set by
J9, which either connects the reference to ground or ties it to the output of the reference buffer. The
reference buffer is initially configured to generate a rail at mid-supply for single supply operation.
Alternatively, this jumper can be left unconnected and the desired voltage can be applied directly to the
VREF test point. It is also possible to connect J7 and configure the reference buffer as an integrator to ac
couple the output as shown in Figure 6.
4.5
Miscellaneous
C1, C2, C3, and C4 are the supply bypass capacitors for the device and are pre-populated with 0.1 µF
and 0.01µF capacitors that usually provide adequate power supply bypassing for U1. Refer to the
difference amplifier data sheet for further information. Similarly, C5, C6, C7, and C8 provide supply
bypassing for U2. Refer to the buffer amplifier data sheet for further information.

Configurations
5.1
Difference Amplifier
This EVM allows for many jumper-selectable configurations. Pins 1, 2, 3, and 5 of the amplifier are routed
to headers that allow the user to define what connections are made to the internal resistors. Note it is
always necessary for either pin 2 or pin 5 to route to the output to ensure closed loop operation with
negative feedback. Figure 5 shows several ways to configure the jumpers and the associated transfer
function. The exact gain depends on the ratio of resistors used in the selected difference amplifier. If the
resistors in the difference amplifier are not all equal, then reciprocal gains can be achieved in each
configuration as shown in the top two figures.

Configurations

5.2
Reference Amplifier
An onboard amplifier provides flexibility in reference configuration. In the default configuration the amplifier
operates as a supply splitter, dividing the positive supply voltage in half and buffering it for single supply
operation.
5.2.1
Buffered Reference Voltage Connection
A buffered-reference configuration is useful when the source impedance is high (for example, a voltage
divider). Buffering a high-impedance source with an operational amplifier provides a low-impedance
source and preserves common-mode rejection. The reference amplifier voltage is derived from the
positive power supply and can be adjusted by changing the R5 and R6.
5.2.2
AC Coupled Output
It is possible to generate an ac coupled output by feeding the output of the diff-amp through an integrator
and back to the reference pin. The output of the integrator will drive the reference such that the dc voltage
at the output of the diff-amp matches the voltage applied to the non-inverting terminal of the reference
amplifier. R5 can be removed if it is desired to ground the input of the amplifier in dual supply operation.
The cutoff frequency will be set by the RC time constant of the integrator. This is sometimes preferable to
using ac coupling capacitors at the input because capacitors tend to have wide tolerance ranges and
mismatch in these capacitors can degrade the common-mode rejection of the amplifier. This can be
implemented by placing a jumper on J7, removing R3, and populating R4 and C9 as shown in Figure 6.
