ADA4937-1YCPZ-R2

Overview

The ADA4937-1YCPZ-R2 is a single-channel, ultralow distortion differential amplifier designed for driving high-performance analog-to-digital converters (ADCs) with resolutions up to 16 bits. Fabricated using Analog Devices' proprietary silicon-germanium complementary bipolar process, it delivers exceptional dynamic performance with an input voltage noise of 2.2 nV/√Hz and a small-signal bandwidth of 1.9 GHz at unity gain. The device features adjustable output common-mode voltage, fast overdrive recovery, and low DC offset, making it suitable for broadband IF applications and data acquisition systems operating between 3.3 V and 5 V supplies.

Feature Summary

• Ultralow harmonic distortion performance optimized for high-resolution ADC interfacing
• High-speed operation with 1.9 GHz bandwidth and 6000 V/μs slew rate
• Adjustable output common-mode voltage for precise ADC input matching
• Internal common-mode feedback loop ensures excellent output balance

Applications

• 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 availability status directly with authorized distributors as supply conditions may vary. Ensure the component meets required environmental standards and temperature ratings for the intended application environment before finalizing procurement.

Selection Notes

Select this component when driving high-resolution ADCs requiring minimal signal degradation. It is ideal for applications demanding wide bandwidth and low noise in single-supply environments. Consider the external resistor network requirements for setting closed-loop gain and verify PCB layout constraints to maximize performance and minimize distortion effects.

Part Context

This part belongs to the ADA4937 family of differential amplifiers, which includes both single-channel (ADA4937-1) and dual-channel (ADA4937-2) variants. The family shares similar core technologies and performance characteristics but differs in channel count and physical packaging. The YCPZ suffix indicates a lead-free LFCSP package configuration.

Replacement Considerations

The ADA4937-2 serves as the dual-channel counterpart within the same product family. Other Ultralow Distortion Differential ADC Drivers from Analog Devices may offer alternative pinouts or performance trade-offs.
