OPA388 - 10MHz, CMOS, Zero-Drift, Zero-Crossover, True RRIO Precision Operational Amplifier

The OPAx388 (OPA388, OPA2388, and OPA4388) series of precision operational amplifiers areultra-low noise, fast-settling, zero-drift, zero-crossover devices that provide rail-to-rail inputand output operation. These features and excellent ac performance, combined with only 0.25 µV ofoffset and 0.005 µV/°C of drift over temperature, makes the OPAx388 ideal for drivinghigh-precision, analog-to-digital converters (ADCs) or buffering the output of high-resolution,digital-to-analog converters (DACs). This design results in superior performance when drivinganalog-to-digital converters (ADCs) without degradation of linearity. The OPA388 (single version)is available in the VSSOP-8, SOT23-5, and SOIC-8 packages. The OPA2388 (dual version) is offered inthe VSSOP-8 and SO-8 packages. The OPA4388 (quad version) is offered in the TSSOP-14 and SO-14packages. All versions are specified over the extended industrial temperature range (–40°C to+125°C).
