Advanced Monolithic Systems AMSOP-77 ULTRA LOW OFFSET VOLTAGE OPERATIONAL AMPLIFIER RoHS compliant FEATURES • Outstanding Linearity • Low VOS overTemperature.…………………. 55µV Max • Excellent VOS Drift………………………. 0.6µV/°C Max • Ultra High Gain………………………….5000V/mV Min • High PSRR……………………………………3µV/V Max • Low Power Consumption…………………….60mW Max APPLICATIONS • High-Gain Instrumentation • Precision Data Acquisition • Precision Integrators • Precision Threshold Detectors • Biomedical Amplifiers 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. ORDERING INFORMATION: TOL.
