ADA4937-2YCPZ-R2

Overview

The ADA4937-2YCPZ-R2 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. The device features a −3 dB bandwidth of 1.9 GHz at unity gain and a slew rate of 6000 V/μs. Input voltage noise is specified at 2.2 nV/√Hz, with a typical offset voltage of 0.5 mV. It utilizes an internal common-mode feedback loop for output balance and even-order harmonic suppression. The component is housed in a 24-lead, 4 mm × 4 mm Lead Frame Chip Scale Package (LFCSP).

Feature Summary

• Ultralow harmonic distortion performance suitable for high-resolution data acquisition.
• Internal common-mode feedback loop ensures exceptional output balance.
• Adjustable output common-mode voltage allows direct matching to ADC inputs.
• Fast overdrive recovery time facilitates rapid signal restoration.

Applications

• Driving high-performance ADCs up to 16-bit resolution.
• Single-ended-to-differential conversion circuits.
• Intermediate frequency (IF) and baseband gain modules.
• Differential buffering applications.

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 requirements for the intended deployment environment.
