Differential Instrumentation Amplifier

At $19.50 (1-9), AD522A Has Module Performance at IC Prices; A Laser-Trimmed Thin-Film Hybrid in Hermetic DIL

The AD522 differential instrumentation amplifier, designed for applications requiring high precision under less-than-ideal operating conditions, multiplies the difference between two input voltages by a fixed gain, from 1 to 1000, determined by a single external resistance. Built on a precision thin-film substrate in a hermetic DIL package, it combines module-like performance with IC-like small size, low cost, and pinout similar to that of the popular monolithic AD521 (Dialogue 9-1).
