2.3.11 OPA2388 Dual, 10-MHz, CMOS, Zero-Drift, Zero-Crossover, True RRIO Precision Operational Amplifier

The OPA2388 is a precision operational amplifier that 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, makes the OPA2388 a great choice 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 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. The OPA2388 (dual version) is offered 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 industrial temperature range of –40°C to +125°C.
