The OPA388-Q1 and OPA2388-Q1 ( OPAx388-Q1) are automotive, low-noise, fast-settling, zero-drift, precision operational amplifiers that provide rail-to-rail input and output operation. Excellent ac performance, combined with only 0.25 µV of offset and 0.005 µV/°C of drift over temperature, make the OPAx388-Q1 a great choice for driving high-resolution, analog-to-digital converters (ADCs) with high accuracy. Zero-crossover technology minimizes any offset change over the common-mode range. The combination of low drift and very low 1/f noise allow the OPAx388-Q1 to monitor and detect faulty conditions without compromising signal integrity.

These devices are specified over the industrial temperature range of –40°C to +125°C.
