The ADA4950-1/ADA4950-2 are gain-selectable versions of the ADA4932-1/ADA4932-2 with on-chip feedback and
gain resistors. They are ideal choicesfor 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/ ADA4950-2 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.
The ADA4950-1/ADA4950-2 are 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.
The low offset and excellent dynamic performance of the ADA4950-x make it well suited for a wide variety of data acquisition
and signal processing applications.
