Texas Instruments OPAx388/OPAx388-Q-1 Precision Op Amps
Texas Instruments OPAx388/OPAx388-Q-1 Precision Operational Amplifiers are ultra-low noise, fast-settling, zero-drift, zero-crossover devices that provide rail-to-rail input and output operation. These devices offer excellent ac performance, combined with only 0.25µV of offset and 0.005µV/°C of drift over temperature. This feature makes the OPAx388/OPAx388-Q-1 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/OPA388-Q-1 (single version) is available in the VSSOP-8, SOT23-5, and SOIC-8 packages. The OPA2388/OPA2388-Q-1 (dual version) is offered in the VSSOP-8 and SO-8 packages. The OPA4388/OPA4388-Q-1 (quad version) is provided in the TSSOP-14 and SO-14 packages. The Texas Instruments OPAx388-Q-1 devices are AEC-Q100 qualified for automotive applications.Features
