The OPA4H838-SEP precision amplifier 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 0.25µV of offset and 0.01µV/°C of drift over temperature, makes the OPA4H838-SEP 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 OPA4H838-SEP is offered in a TSSOP-14 package. The OPA4H838-SEP is specified from –55°C to +125°C.
