Texas Instruments' OPA388 precision operational amplifier is an ultra-low noise, fast-settling, zero-drift, zero-crossover device that provides rail-to-rail input and output operation. These features and excellent AC performance, combined with only 0.25 µV of offset and 0.005 µV/°C of drift over temperature, make the OPA388 ideal for driving high-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 driving analog-to-digital converters (ADCs) without degradation of linearity. The OPA388 (single version) is available in the VSSOP-8, SOT23-5, and SOIC-8 packages. They are specified over the extended industrial temperature range (-40°C to +125°C).
