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

 

Description

The OPAx188-Q1 operational amplifier family uses TI’s proprietary zero drift 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 family 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 OPA188-Q1 and OPA2188-Q1 are both 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.
