GENERAL DESCRIPTION
The ADA4932-x is the next generation AD8132 with higher performance, and lower noise and power consumption. It is an ideal choice for driving high performance ADCs as a single-ended to-differential or differential-to-differential amplifier. The output common-mode voltage is user adjustable by means of an internal common-mode feedback loop, allowing the ADA4932-x output to match the input of the ADC. The internal feedback loop also provides exceptional output balance as well as suppression of even-order harmonic distortion products.
