The ADA4938-1ACPZ-R2 is a low noise ultralow distortion high speed Differential Amplifier ideal for driving high performance ADCs with resolutions up to 16 bits from DC to 27MHz or up to 12 bits from DC to 74MHz. The output common-mode voltage is adjustable over a wide range, allowing the ADA4938 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-x. A simple external feedback network of four resistors determines the closed-loop gain of the amplifier.
