The ADA4932-1 / ADA4932-2 are the next generation AD8132
with higher performance and lower noise and power consumption.
They are 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 ADA4932-1 / ADA4932-2 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.
With the ADA4932-1 / ADA4932-2, differential gain configurations
are easily realized with a simple external four-resistor feedback
network that determines the closed-loop gain of the amplifier.
The ADA4932-1 / ADA4932-2 were 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
ADA4932-1/ADA4932-2 make them 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 pinouts are
optimized to facilitate the printed circuit board (PCB) layout
and minimize distortion. The ADA4932-1/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.
