ADA4932-2YCPZ-R7

Overview

The ADA4932-2YCPZ-R7 is a dual-channel, low-power differential ADC driver manufactured by Analog Devices Inc. It features a −3 dB bandwidth of 560 MHz at G = 1 and a slew rate of 2800 V/µs. The device operates on supplies between +3 V and ±5 V with a quiescent current of 9.6 mA per amplifier. It provides an adjustable output common-mode voltage via an internal feedback loop to match ADC inputs. Packaged in a 24-lead LFCSP, it supports single-ended-to-differential or differential-to-differential conversion.

Feature Summary

• Internal common-mode feedback loop ensures exceptional output balance and suppresses even-order harmonic distortion without requiring tightly matched external components.
• User-adjustable output common-mode voltage allows precise matching to the input requirements of high-performance analog-to-digital converters.
• Differential gain configurations are easily realized using a simple external four-resistor feedback network that determines the closed-loop gain.

Applications

• ADC drivers
• Single-ended-to-differential converters
• IF and baseband gain blocks
• Differential buffers
• Line drivers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the intended supply voltage range and temperature operating conditions before procurement. Cross-reference the component marking with the datasheet pinout configuration to prevent installation errors during assembly.

Selection Notes

Select this component for applications requiring high-speed signal conversion with low power consumption. The dual-channel architecture is suitable for processing two independent signals within a compact footprint. Consider the 24-lead LFCSP package dimensions when designing the PCB layout to ensure adequate thermal dissipation and signal integrity for high-frequency operation.

Part Context

This device belongs to the ADA4932 series, representing the next generation of ADI's differential amplifiers. It succeeds the AD8132 model, offering improved performance metrics including lower noise and reduced power consumption. The series utilizes a proprietary silicon-germanium complementary bipolar process to achieve low distortion levels while maintaining high dynamic performance for data acquisition systems.

Replacement Considerations

The AD8132 is documented as the predecessor to this device family. Verify pinout compatibility and electrical parameter differences when substituting legacy components in existing designs.
