OPA188 (ACTIVE)

Precision, Low-Noise, Rail-to-Rail Output, 36V Zero-Drift Operational Amplifier

Precision, Low-Noise, Rail-to-Rail Output, 36V Zero-Drift Operational Amplifier  - OPA188
 

Description

The OPA188 operational amplifier uses TI’s proprietary auto-zeroing techniques to provide low offset voltage (25-µV maximum) and near zero-drift over time and temperature. This miniature, high-precision, low-quiescent current amplifier offers high input impedance and rail-to-rail output swing within 15 mV of the rails. The input common-mode range includes the negative rail. Either single or dual supplies can be used in the range from 4 V to 36 V (±2 V to ±18 V).

The single version is available in the MicroSIZE SOT-23-5, MSOP-8, and SO-8 packages. All versions are specified for operation from –40°C to +125°C.
