GENERAL DESCRIPTION

The ADA4932 family 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

family 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 ADA4932 family 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 family make it well

suited for a wide variety of data acquisition and signal processing

applications.

The ADA4932-1 is available in a 16-lead LFCSP and the

ADA4932-2 is available in a 24-lead LFCSP. The pinout has been

optimized to facilitate PCB layout and minimize distortion. The

ADA4932 family is specified to operate over the −40°C to

+105°C temperature range; both operate on supplies between

+3 V and 5 V.

With the ADA4932 family, differential gain configurations are

easily realized with a simple external four-resistor feedback

network that determines the closed-loop gain of the amplifier.
