OPA2188AIDGKT

The OPA2188AIDGKT from Texas Instruments is a high-precision, low-power operational amplifier utilizing auto-zeroing techniques for minimal offset voltage and drift. It boasts a low offset voltage of 25 µV (max) and an impressive offset voltage drift of 0.03 µV/°C, ensuring stable performance over time and temperature.

This amplifier operates with a wide supply range, from ±2 V to ±18 V dual supplies or 4.0 V to 36 V single supplies. It offers a low noise characteristic of 8.8 nV/√Hz and a 0.1-Hz to 10-Hz noise of 0.25 µVPP. The device provides excellent DC precision with high PSRR (142 dB) and CMRR (146 dB), and a significant open-loop gain of 136 dB.

The OPA2188AIDGKT features a rail-to-rail output and an input common-mode range that includes the negative rail. It is RFI filtered, making it suitable for sensitive applications. The device is available in MSOP-8 and SO-8 micro-size packages and is specified for operation in temperatures ranging from -40°C to +105°C.

Applications for the OPA2188AIDGKT include bridge amplifiers, strain gauges, test equipment, transducer applications, temperature measurement, electronic scales, medical instrumentation, resistance temperature detectors, and precision active filters.
