ADA4927-1YCPZ-R2

Overview

The ADA4927-1YCPZ-R2 is a single-channel, ultralow distortion current feedback differential amplifier designed to drive high-performance analog-to-digital converters (ADCs) with resolutions up to 16 bits. It operates from DC to 100 MHz and features a 2.3 GHz small-signal bandwidth with a 5000 V/µs slew rate. The device utilizes an internal common-mode feedback loop for exceptional output balance and even-order harmonic suppression. It supports wide supply operation ranging from 4.5 V to 11 V and includes a power-down pin for low-power management.

Feature Summary

• Current feedback architecture provides stable bandwidth independent of closed-loop gain settings
• Internal common-mode feedback loop ensures high output balance and suppresses even-order distortion products
• Adjustable output common-mode voltage allows precise matching to ADC input requirements
• Silicon-germanium complementary bipolar process enables extremely low harmonic distortion and noise

Applications

• Driving high-resolution ADCs in data acquisition systems
• Single-ended-to-differential signal conversion
• Intermediate frequency (IF) and baseband gain blocks
• Differential line drivers and buffers

Procurement Notes

Verify the specific ordering suffix R2 against the manufacturer's official documentation to confirm reel packaging specifications. Ensure compatibility with standard surface-mount reflow profiles for LFCSP packages. Confirm that the component meets RoHS compliance standards required for your manufacturing environment before finalizing procurement orders.

Selection Notes

Select this component when driving 14-bit or 16-bit ADCs requiring high dynamic range at frequencies up to 100 MHz. The current feedback topology is preferred over voltage feedback amplifiers for maintaining consistent bandwidth at higher gains. Consider the adjustable VOCM pin if the target ADC requires a specific common-mode voltage level different from the system ground.

Part Context

This part belongs to the ADA4927 family of differential ADC drivers manufactured by Analog Devices Inc. using silicon-germanium technology. The -1 designation indicates a single-channel configuration housed in a 16-lead LFCSP package. The series is optimized for applications demanding low noise and high linearity in signal processing chains.
