ADA4932-1YCPZ-R7

Overview

The ADA4932-1YCPZ-R7 is a low-power, single-channel differential ADC driver fabricated using Analog Devices' proprietary silicon-germanium complementary bipolar process. It features a −3 dB small-signal bandwidth of 560 MHz at G = 1 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 adjustable output common-mode voltage via an internal feedback loop and supports differential-to-differential or single-ended-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.
• External four-resistor feedback network enables flexible gain configuration, including fractional differential gains less than unity.

Applications

• Driving high-performance analog-to-digital converters
• Single-ended-to-differential signal conversion
• Intermediate frequency and baseband gain blocks
• Differential buffering applications

Procurement Notes

Verify that the specific suffix YCPZ-R7 corresponds to the 16-lead LFCSP package and tape-and-reel shipping format as defined in the manufacturer's ordering guide. Confirm that the component meets the required RoHS compliance standards for your manufacturing environment. Ensure proper ESD handling procedures are followed during storage and assembly due to the sensitivity of the silicon-germanium process technology.

Selection Notes

Select this component when a low-noise, high-speed differential driver is required for driving ADCs with minimal power consumption. The device is suitable for applications needing independent control of differential gain and output common-mode levels. Consider the 16-lead LFCSP package constraints and thermal dissipation characteristics relative to the ambient operating temperature range of −40°C to +105°C.

Part Context

The ADA4932-1 serves as the next-generation successor to the AD8132, offering improved performance metrics including higher bandwidth and lower noise figures. It belongs to the ADA4932-x family, which also includes the dual-channel ADA4932-2 variant housed in a 24-lead package. Both devices share the same functional architecture and are designed to facilitate optimized PCB layout for minimized distortion.

Replacement Considerations

The AD8132 is the predecessor model within the same product lineage. While functionally similar, the ADA4932-1 offers enhanced speed and lower power consumption. Verify pinout compatibility and ensure that the application circuit can accommodate the updated electrical specifications before substitution.
