OPA2188 - 0.03µV/°C, 6µV Vos, Low Noise, Rail-to-Rail Output, 36V Zero-Drift Operational Amplifier

Updated : 2020-01-09 14:18:32
Description

The OPA2188 operational amplifier uses TI 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 of 4 V to 36 V (±2 V to ±18 V).

The OPA2188 device is available in MSOP-8 and SO-8 packages. The device is specified for operation from –40°C to +105°C.
