Precision Operational Amplifier
The OPA177 precision bipolar op amp feature very low offset voltage and drift. Laser-trimmed offset, drift and input bias current virtually eliminate the need for costly external trimming. The high performance and low cost make them ideally suited to a wide range of precision instrumentation. The low quiescent current of the OPA177 dramatically reduce warm-up drift and errors due to thermoelectric effects in input interconnections. It provides an effective alternative to chopper-stabilized amplifiers. The low noise of the OPA177 maintains accuracy.
Features
* Low offset voltage: 25uV max.
* Low drift: 0.3uV/°C
* High open-loop gain: 130dB min.
* Low quiescent current: 1.5mA typ.
* Replaces industry-standard op amps: OP-07, OP-77, OP-177, AD707, etc.
Applications
* Precision instrumentation
* Data acquisition
* Test equipment
* Bridge amplifier
* Thermocouple amplifier
