ADA4937-1YCPZ-R7

Overview

The ADA4937-1YCPZ-R7 is a single-channel, low-noise, ultralow distortion, high-speed differential amplifier fabricated using Analog Devices' proprietary silicon-germanium (SiGe) complementary bipolar process. Designed for driving high-performance analog-to-digital converters (ADCs) with resolutions up to 16 bits from DC to 100 MHz, it features an adjustable output common-mode voltage and internal common-mode feedback for exceptional output balance. The device operates on a single supply between 3.3 V and 5 V, offering 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. It is housed in a 16-lead, 3 mm × 3 mm lead-free LFCSP package.

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 for direct ADC interface matching
• Fast overdrive recovery time for rapid signal restoration

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 tape-and-reel packaging and temperature grade specifications. Ensure compatibility with the required PCB footprint and thermal management requirements for the 16-lead LFCSP package before finalizing procurement plans.

Selection Notes

Select this component when driving high-speed ADCs requiring minimal signal degradation. The adjustable VOCM pin allows precise alignment with ADC input ranges. Consider the external four-resistor feedback network for setting closed-loop gain. Evaluate power dissipation limits relative to ambient temperature and board layout constraints.

Part Context

This part belongs to the ADA4937 family of differential amplifiers, which also includes the dual-channel ADA4937-2 variant. Both share identical electrical characteristics but differ in channel count and package configuration. The family utilizes SiGe technology to achieve superior linearity and speed compared to standard bipolar processes.

Replacement Considerations

The ADA4937-2 serves as the dual-channel equivalent within the same product family. Verify pinout compatibility and channel requirements when substituting.
