DESCRIPTION
The PA13 is a state of the art high voltage, very high
output current operational amplifier designed to drive
resistive, inductive and capacitive loads. For optimum
linearity, especially at low levels, the output stage is
biased for class A/B operation using a thermistor com-
pensated base-emitter voltage multiplier circuit. The
safe operating area (SOA) can be observed for all op-
erating conditions by selection of user programmable
current limiting resistors. For continuous operation un-
der load, a heatsink of proper rating is recommended.
The PA13 is not recommended for gains below –3 (in-
verting) or +4 (non-inverting).
This hybrid integrated circuit utilizes thick film (cermet)
resistors, ceramic capacitors and semiconductor chips
to maximize reliability, minimize size and give top per-
formance. Ultrasonically bonded aluminum wires pro-
vide reliable interconnections at all operating temper-
atures. The 12-pin power SIP package is electrically
isolated.

NOTES: 1. (All Min/Max characteristics and specifications are guaranteed over the Specified Operating Condi-
tions. Typical performance characteristics and specifications 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 specification of PA13A is identical to the specification for PA13 in the applicable column to the left
3. The power supply voltage for all tests is ±40, 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. Full temperature range specifications are guaranteed but not 100% tested.
