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.
With the ADA4932-x, differential gain configurations are easily
realized with a simple external four-resistor feedback network that
determines the closed-loop gain of the amplifier.
The ADA4932-x is fabricated using the Analog Devices, Inc.,
proprietary silicon-germanium (SiGe) complementary bipolar
process, enabling it to achieve low levels of distortion and noise
at low power consumption. The low offset and excellent dynamic
performance of the ADA4932-x make it well suited for a wide
variety of data acquisition and signal processing applications.
