ADA4927-1YCPZ-R7

Overview

The ADA4927-1YCPZ-R7 is a single-channel, ultralow distortion current feedback differential amplifier designed for driving high-performance ADCs up to 16-bit resolution. It features a 2.3 GHz small-signal bandwidth and a 5000 V/µs slew rate. The device operates on supply voltages from 4.5 V to 11 V with a typical quiescent current of 22.1 mA per amplifier. It includes an internal common-mode feedback loop for output balance and offers externally adjustable gain via a four-resistor network.

Feature Summary

• Current feedback architecture provides wide bandwidth and low distortion at higher gains compared to voltage feedback amplifiers.
• Internal common-mode feedback loop ensures exceptional output balance and suppression of even-order distortion products.
• Adjustable output common-mode voltage allows easy matching to required ADC input levels.
• Fabricated using silicon-germanium complementary bipolar process for very low noise and distortion.

Applications

• ADC drivers
• Single-ended-to-differential converters
• IF and baseband gain blocks
• Differential buffers
• Differential 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 operating temperature range and supply voltage requirements before procurement. Cross-reference the datasheet revision history for any parameter updates or pinout changes that may affect integration.

Selection Notes

Select this component when driving high-resolution ADCs requiring wide bandwidth and low harmonic distortion. The current feedback design is advantageous for maintaining stability and performance across varying closed-loop gains. Consider the external feedback resistor values carefully, as they primarily determine bandwidth and stability rather than noise gain.

Part Context

This part belongs to the ADA4927 series of differential amplifiers, which also includes the dual-channel ADA4927-2 variant. Both versions share similar electrical characteristics but differ in packaging; the ADA4927-1 utilizes a 16-lead LFCSP package optimized for PCB layout and distortion minimization.

Replacement Considerations

The ADA4927-2 serves as the dual-channel alternative within the same family. Verify if the application requires multiple channels or if the single-channel configuration suffices. No other direct substitutes are confirmed in the provided documentation.
