TI OPA388IDBVR

The OPAx388 (OPA388, OPA2388, and OPA4388) series of precision operational amplifiers are ultra-low noise, fast-settling, zero-drift, and zero-crossing devices that can operate with rail-to-rail inputs and outputs. These features, combined with excellent AC performance, an offset voltage of only 0.25µV, and a temperature drift of 0.005µV/°C, make the OPAx388 an ideal choice for driving high-precision analog-to-digital converters (ADCs) or buffering the outputs of high-resolution digital-to-analog converters (DACs). This design offers excellent performance when driving analog-to-digital converters (ADCs) without degrading linearity. The OPA388 (single-channel version) is available in three packages: VSSOP - 8, SOT23 - 5, and SOIC - 8. The OPA2388 (dual-channel version) is available in two packages: VSSOP - 8 and SO - 8. The OPA4388 (quad-channel version) is available in two packages: TSSOP - 14 and SO - 14. All versions are rated for an operating temperature range of -40°C to +125°C. The OPA388 supports high-precision, low-error measurements.
