ADA4937-1YCPZ-R7

ADA4937-1YCPZ-R7 is a low noise, ultralow distortion, high speed differential amplifier. It is a ideal choice for driving high performance ADC with resolutions up to 16bits from DC to 100MHz. The adjustable level of the output common mode allows theADA4937-1 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. With the ADA4937-1 differential gain configurations are easily realized with a simple external feedback network of four resistors that determine the closed-loop gain of the amplifier. Typical application includes ADC drivers, single-ended-to-differential converters, IF and baseband gain blocks, differential buffers and line drivers.
