PA107DP

GENERAL DESCRIPTION

The PA107DP is a state of the art wideband high pow-

er operational amplifier designed to drive resistive, ca-

pacitive or inductive loads. For optimum linearity the

output stage is biased for class A/B operation. Feed

forward technology is used to obtain wide bandwidth

and excellent DC performance, but constricts use to

inverting mode only. External compensation allows the

user to obtain both high gain and wide bandwidth. Use

of a heatsink is required to realize the SOA.

This hybrid integrated circuit uses thick film resistors,

ceramic capacitors, and semiconductors to maximize

reliability, minimize size, and give top performance.

Ultrasonically bonded aluminum wires provide reliable

interconnections at all operating temperatures. The 12

pin SIP package occupies only 2 square inches. The

use of compressible insulation washers voids the war-

ranty.
