The OPA862 is a single-ended-to-differential amplifier that interfaces single-ended sources to differential-input analog-to-digital converters (ADCs). The device only consumes 3.1-mA quiescent current for an output-referred noise density of 8.3 nV/√Hz in a gain of 2-V/V configuration. The device can be configured for other gains using external resistors. The device has a large gain-bandwidth product of 400 MHz and a slew rate of 130 V/μs. This yields exceptional linearity and fast-settling, 18-bit performance over comparable single-ended-to-differential ADC drivers. The device includes a reference input pin for setting the output common-mode voltage.
