ADA4932-1YCPZ-RL

Overview

The ADA4932-1YCPZ-RL is a low-power, high-speed differential ADC driver manufactured by Analog Devices Inc. It features a −3 dB bandwidth of 560 MHz at unity gain and a slew rate of 2800 V/µs. 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 input voltage noise density of 3.6 nV/√Hz and achieves a spurious-free dynamic range (SFDR) of 100 dB at 10 MHz. The component is housed in a 16-lead LFCSP package and supports operation across a temperature range of −40°C to +105°C.

Feature Summary

• Utilizes proprietary silicon-germanium complementary bipolar process for low distortion and noise
• Features internal common-mode feedback loop for exceptional output balance and even-order harmonic suppression
• Supports single-ended-to-differential or differential-to-differential conversion via external four-resistor network
• Includes power-down pin functionality for reduced standby current consumption

Applications

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

Procurement Notes

Verify the specific ordering suffix RL indicates reel packaging configuration. Confirm the YCPZ designation corresponds to the lead-free 16-lead LFCSP package variant. Ensure compatibility with the intended PCB footprint and thermal management requirements for the exposed paddle connection.

Selection Notes

Select this component when driving high-performance ADCs requiring low noise and high linearity. Consider the adjustable output common-mode voltage feature for matching ADC input ranges. Evaluate the 560 MHz bandwidth against signal frequency requirements. Verify that the 9.6 mA quiescent current aligns with system power constraints.

Part Context

The ADA4932-1 is part of the ADA4932 series, serving as the next-generation successor to the AD8132. It offers improved performance metrics including higher bandwidth and lower power consumption. The device is designed for data acquisition and signal processing applications where precise differential signaling is critical.

Replacement Considerations

The AD8132 is identified as the predecessor model. Verify pinout compatibility and electrical parameter differences before substitution. No other direct substitute part numbers are confirmed in the provided documentation.
