ADA4938-1ACPZ-R7

ADA4938-1 is a low noise, ultralow distortion, high speed differential amplifier. It is an ideal choice for driving high performance ADC with resolutions up to 16bits from DC to 27MHz, or up to 12bits from DC to 74MHz. The output common-mode voltage is adjustable over a wide range, allowing the ADA4938-1 to match the input of the ADC. The internal common-mode feedback loop also provides exceptional output balance as well as suppression of even-order harmonic distortion products. Full differential and single-ended-to-differential gain configurations are easily realized with the ADA4938-1. Typical application includes ADC drivers, single-ended-to-differential converters, IF and baseband gain blocks, differential buffers and line drivers.
