GENERAL DESCRIPTION
The AMSOP-77 is a precision operational amplifier with an ultra low input offset voltage. This device features a wide input
voltage range of
±13V
minimum, low input bias current, high impedance, high PSRR, high CMRR, excellent stability of
offsets and gain over time and temperature. Exceptional gain linearity eliminates incorrectable system nonlinearities common
in previous monolithic op amps, and provides superior performance in high closed-loop gain applications.
Low cost, low noise, low offsets and high open-loop gain make the AMSOP-77 an excellent choice particularly for high-gain
instrumentation applications. Other applications include precision data acquisition, precision integrators, threshold detectors
and medical instrumentation.
The AMSOP-77 is operational in the commercial temperature range of 0°C to 70°C and is available in the 8 lead SOIC and
plastic dip (PDIP) packages.
