ADA4932-1YCPZ-R2

Overview

The ADA4932-1YCPZ-R2 is a low-power, high-speed differential ADC driver manufactured by Analog Devices Inc. It features a 560 MHz small-signal bandwidth and a 2800 V/µs slew rate at unity gain. The device operates on supply voltages ranging from +3 V to ±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 and includes a power-down pin for energy management. Packaged in a 16-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 downstream analog-to-digital converters.
• Flexible gain configuration using a simple external four-resistor feedback network that supports gains less than one.
• Integrated power-down functionality enables significant reduction in power consumption when the device is not actively processing signals.

Applications

• Driving high-performance analog-to-digital converters (ADCs)
• Single-ended-to-differential signal conversion
• Intermediate frequency (IF) and baseband gain modules
• Differential buffering applications

Procurement Notes

Verify the specific ordering suffix R2 corresponds to tape-and-reel packaging when sourcing this component. Confirm that the 16-lead LFCSP package variant matches the required PCB footprint dimensions. Ensure the selected temperature grade covers the intended operating environment range of −40°C to +105°C. Cross-reference the datasheet revision F specifications against the manufacturing date code to ensure parameter consistency.

Selection Notes

Select this component for designs requiring high dynamic range and low noise in compact form factors. The SiGe complementary bipolar process offers superior speed and lower power compared to previous generations like the AD8132. Consider the 16-lead LFCSP package for space-constrained layouts where thermal dissipation can be managed through exposed pad soldering. Evaluate the need for external feedback resistors to set the desired closed-loop gain and input impedance.

Part Context

This part belongs to the ADA4932 series, which serves as the next-generation successor to the AD8132 family. The series includes both single-channel (ADA4932-1) and dual-channel (ADA4932-2) variants. All members share similar architectural benefits, including low distortion, low noise, and adjustable common-mode control, optimized for driving precision data acquisition systems.

Replacement Considerations

The ADA4932-1 is the direct upgrade replacement for the AD8132, offering improved performance metrics. Designers transitioning from the AD8132 should verify that the existing PCB layout accommodates the 16-lead LFCSP package dimensions and that the thermal design supports the specified junction temperature limits.
