The OPAx388 (OPA388, OPA2388, and OPA4388) series of precision
operational amplifiers 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 only 0.25 µV of offset and 0.005 µV/°C of drift over
temperature, makes the OPAx388 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. |
