Power Operational Amplifier

PA13 • PA13A

P r o d u c t I n n o v a t i o n F r o m

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.
