The ADA4950-1YCPZ-R7 is a low power selectable gain Differential ADC Driver. It is ideal choices for driving high performance ADCs as single-ended-to-differential or differential-to-differential amplifiers. The output common-mode voltage is user adjustable by means of an internal common-mode feedback loop, allowing the ADA4950-1 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. Differential gain configurations of 1, 2 and 3 are easily realized with internal feedback networks that are connected externally to set the closed-loop gain of the amplifier. The ADA4950-1 is fabricated using the Analog Devices, Inc., proprietary silicon-germanium (SiGe) complementary bipolar process, enabling them to achieve low levels of distortion and noise at low power consumption.
