Precision operational amplifier ideal for driving high-precision ADCs or DACs

The Texas Instruments OPAx388 (OPA388, OPA2388, and OPA4388) series of precision operational amplifiers are fast-settling, ultra-low noise, zero-drift, zero-crossover devices that provide rail-to-rail input and output operation. These options and excellent AC performance, coupled with only 0.25µV of offset and 0.005µV/C of drift over temperature, makes the OPAx388 perfect for driving high-precision, ADCs or buffering the output of high-resolution, DACs. This design produces a superior performance when driving ADCs with no degradation of linearity. The OPA388 (single version) is offered in the VSSOP-8, SOT23-5, and SOIC-8 packages. The OPA2388 (dual version) is provided in the VSSOP-8 and SO-8 packages. The OPA4388 (quad version) is offered in the TSSOP-14 and SO-14 packages. All versions are specified over the extended industrial temperature range (–40C to +125C).
