PA16, PA16A
Power Operational Amplifiers
FEATURES
DESCRIPTION
The PA16 and PA16A are wideband, high output current operational ampliiers designed to drive resistive,
inductive and capacitive loads. Their complementary
“collector output” stage can swing close to the supply
rails and is protected against inductive kickback. For
optimum linearity, the output stage is biased for class
A/B operation. The safe operating area (SOA) can be
observed for all operating conditions by selection of
user programmable, current limiting resistors (down to
10mA). Both ampliiers are internally compensated but
are not recommended for use as unity gain followers.
For continuous operation under load, mounting on a
heatsink of proper rating is recommended.
These hybrid integrated circuits utilize thick ilm (cermet) resistors, ceramic capacitors and semiconductor
chips to maximize reliability, minimize size and give
top performance. Ultrasonically bonded aluminum
wires provide reliable interconnections at all operating
temperatures. The Power SIP package is electrically
isolated.

NOTES:
1. (All Min/Max characteristics and speciications are guaranteed over the Speciied Operating Conditions. Typical performance characteristics and speciications are derived from measurements taken
at typical supply voltages and TC = 25°C).
2. Long term operation at the maximum junction temperature will result in reduced product life. Derate
power dissipation to achieve high MTTF.
* The speciication of PA16A is identical to the speciication for PA16 in applicable column to the left.
3. The power supply voltage for all speciications is the TYP rating unless otherwise noted as a test
condition.
4. +VS and –VS denote the positive and negative supply rail respectively. Total VS is measured from +VS
to –VS.
5. Rating applies if the output current alternates between both output transistors at a rate faster than
60Hz.
6. Exceeding CMV range can cause the output to latch.
7. Full temperature speciications are guaranteed but not 100% tested.
8. The absolute maximum negative input voltage is equal to the negative power supply voltage plus 1V
(-VS + 1V).
TYPICAL APPLICATION
Vehicular Sound System Power Stage
100K
When system voltages are low and power is at a premium, the PA16 is a natural choice. The circuit above
utilizes not only the feature of low internal loss of the
PA16, but also its very low distortion level to implement a crystal clear audio ampliier suitable even for
airborne applications. This circuit uses AC coupling
of both the input signal and the gain circuit to render
DC voltage across the speaker insigniicant. The resistor and capacitor across the inputs form a stability enhancement network. The 0.27 ohm current limit
resistors provide protection in the event of an output
short circuit.

The SOA curves combine the effect of all limits for this Power Op Amp. For a given application, the direction and magnitude of the output current should be calculated or measured
and checked against the SOA curves. This is simple for resistive loads but more complex for reactive and EMF generating loads. The following guidelines may save extensive
analytical efforts:
The ampliier can handle any EMF generating or reactive
load and short circuits to the supply rails or shorts to common if the current limits are set as follows at TC = 85°C.

These simpliied limits may be exceeded with further analysis using the operating conditions for a speciic application.
CURRENT LIMIT
Proper operation requires the use of two current limit resistors, connected as shown in the external connection diagram. The minimum value for RCL is 0.12 ohm, however for optimum reliability it should be set as high as possible.
Refer to the “General Operating Considerations” section of the handbook for current limit adjust details.
RCL = 0.65 - 0.01

DEVICE MOUNTING
The case (mounting lange) is electrically isolated and should be mounted directly to a heatsink with thermal compound. Screws with Belville spring washers are recommended to maintain positive clamping pressure on heatsink
mounting surfaces. Long periods of thermal cycling can loosen mounting screws and increase thermal resistance.
Since the case is electrically isolated (loating) with respect to the internal circuits it is recommended to connect it
to common or other convenient AC ground potential.
