ADA4937-2YCPZ-R7

Overview

The ADA4937-2YCPZ-R7 is a dual-channel, ultralow distortion differential amplifier designed for driving high-performance analog-to-digital converters (ADCs) with resolutions up to 16 bits. It operates on a single supply between 3.3 V and 5 V. Key electrical parameters include a small-signal bandwidth of 1.9 GHz at unity gain, a slew rate of 6000 V/µs, and an input voltage noise of 2.2 nV/√Hz. The device features adjustable output common-mode voltage and externally adjustable gain via a four-resistor feedback network.

Feature Summary

• Extremely low harmonic distortion performance across wide frequency ranges
• Internal common-mode feedback loop ensures exceptional output balance
• Adjustable output common-mode voltage matches ADC input requirements
• Fast overdrive recovery time minimizes transient settling delays

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the operating temperature range aligns with your system's environmental constraints before finalizing procurement.

Selection Notes

Select this component when driving ADCs requiring high dynamic range and minimal signal distortion. The dual-channel configuration allows for cost-effective implementation in multi-channel data acquisition systems. Verify that the external feedback resistor values match the desired closed-loop gain while maintaining stability within the specified bandwidth limits.

Part Context

This part belongs to the ADA4937 family of differential amplifiers manufactured using Analog Devices' proprietary silicon-germanium complementary bipolar process. The YCPZ suffix indicates a lead-free 24-lead LFCSP package optimized for PCB layout to minimize distortion. The R7 suffix denotes tape and reel packaging suitable for automated surface-mount assembly.

Replacement Considerations

The ADA4937-1YCPZ-R7 serves as the single-channel equivalent within the same family. Other members of the ADA4937 series may offer similar performance characteristics but differ in channel count or package dimensions.
