Texas Instruments' OPA4388 precision op-amps are ultra-low noise, fast-settling, zero-drift, zero-crossover devices that provide rail-to-rail input and output operation. These features and excellent AC performance, combined with 0.25 µV offset and 0.005 µV/°C drift overtemperature makes the OPA4388 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 excellent performance when driving ADCs without degradation of linearity. The OPA4388 (quad) is offered in the TSSOP-14 and SO-14 packages. The op-amps are specified over the industrial temperature range of -40°C to +125°C.
