The MSK 3554 is a pin compatible, low gain stable, drop-in replacement for the OPA 3554 and TP 3554. The MSK 3554 does not exhibit high frequency output oscillations like other versions of the 3554 when operated at closed loop gains of less than 55 V/V. The extremely low input bias current and input offset voltage ratings coupled with a high slew rate and wide bandwidth make the MSK 3554 an excellent choice for fast D/A converters, buffers, pulse amplifiers and other high speed op-amp applications. The MSK 3554 is packaged in an 8-pin TO-3 using thick film hybrid technology to obtain high reliability and compact size.
