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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed.
Note 2: Long-Term Input Offset Voltage Stability refers to the averaged trend line of VOS vs. Time over extended periods after the first 30 days of operation.
Excluding the initial hour of operation, changes in VOS during the first 30 operating days are typically 2.5mV. Parameter is sample tested.
Note 3: Sample tested
Note 4: Guaranteed by design.
Note 5: Guaranteed by end-point limits.

amps. The OP-77E CMRR of 1mV/V assures errors of less than 2ppm.
