GENERAL DESCRIPTION

–80

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.

Figure 3. Harmonic Distortion vs. Frequency at Various Gains

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 available in a Pb-free, 3 mm × 3 mm 16-lead

LFCSP (ADA4932-1, single) or a Pb-free, 4 mm × 4 mm 24-lead

LFCSP (ADA4932-2, dual). The pinout has been optimized to

facilitate PCB layout and minimize distortion. The ADA4932-1

and the ADA4932-2 are specified to operate over the −40°C to

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

+3 V and 5 V.

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.
