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.

Evaluation Kits (1)
The EVAL-FDA-2CPZ-24 is designed to aid in the evaluation of dual high speed differential amplifiers. The EVAL-FDA-2CPZ-24 is a bare board (that is, there are no components soldered to the board) that enables users to quickly prototype a variety of differential amplifier circuits, which minimizes risk and reduces time to market. The EVAL-FDA-2CPZ-24 evaluation board supports any of the Analog Devices, Inc., dual high speed differential amplifiers in 4 mm × 4 mm, lead frame chip scale packages (LFCSP).
Tools & Simulations
Precision ADC Driver Tool
The Precision ADC Driver Tool is a web application that simulates the performance of precision ADC and driver combinations. Potential issues with driver selection, kickback settling, and distortion are flagged, and design tradeoffs can be quickly evaluated. Simulations and calculations include system noise, distortion, and settling of the ADC input
