situations such as down hole instrumentation. The amplifier

can power mechanical or electronic transducers and can drive

the long transmission lines associated with these applications.

for operation at a case temperature of 200°C. To meet the

high temperature requirements for up to 200 hours, polyimid

has replaced the standard epoxy for attaching the small signal

devices.

ceramic capacitors and silicon semiconductors to maximize

reliability, minimize size and give top performance. Ultrasoni-

cally bonded aluminum wires provide reliable interconnections

at all operating temperatures. The 8-pin TO-3 package (see

Package Outlines) is hermetically sealed and isolated. The use

of compressible thermal washers and/or improper mounting

torque will void the product warranty. Please see “General

Operating Considerations” .
