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.
