OPA188-Q1 - Automotive-Qualified Precision, Low-Noise, RRO, 36V, Zero-Drift Operational Amplifier

Updated : 2020-01-09 14:18:23
Description

The OPAx188-Q1operational amplifier family uses TI’s proprietary zero drift techniques toprovide low offset voltage (25-µV maximum) and near zero-drift over time and temperature. This miniature, high-precision,low-quiescent current amplifier family offers high input impedanceand rail-to-rail output swing within 15 mV of the rails. The input common-mode range includes thenegative rail. Either single or dual supplies can be used in the range from 4 V to 36 V (±2 V to±18 V).

The OPA188-Q1 and OPA2188-Q1 areboth offered in VSSOP-8. The single-channel version
(OPA188-Q1) is fully specified from –40°C to +125°C, and the dual-channel version(OPA2188-Q1) is fully specified from –40°C to +105°C.
