  • Low input voltage noise: 3.6 nV/√Hz
  • ±0.5 mV typical input offset voltage
  • Externally adjustable gain
  • Can be used with gains less than 1
  • Differential-to-differential or single-ended-to-differential operation
  • Adjustable output common-mode voltage

  • Wide supply range: +3 V to ±5 V
  • Available in 16-lead and 24-lead LFCSP packages

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.
