ADA4939-1YCPZ-R2

Overview

The ADA4939-1YCPZ-R2 is a single-channel, ultralow distortion differential amplifier designed for driving high-performance ADCs. It features a 1.4 GHz small-signal bandwidth and a 6800 V/µs slew rate at G=2. The device operates on a single supply between 3.0 V and 5.25 V, consuming approximately 36.5 mA per amplifier. It utilizes a proprietary silicon-germanium process to achieve an input voltage noise of 2.3 nV/√Hz and second harmonic distortion of -102 dBc at 10 MHz. The component is housed in a 16-lead LFCSP package.

Feature Summary

Ultralow harmonic distortion performance with exceptional output balance via internal common-mode feedback loop
High-speed operation with 1.4 GHz bandwidth and fast overdrive recovery under one nanosecond
Low input voltage noise of 2.3 nV/√Hz utilizing silicon-germanium complementary bipolar technology
Adjustable output common-mode voltage allowing precise matching to ADC input requirements

Applications

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

Procurement Notes

Verify the specific ordering suffix R2 corresponds to tape and reel packaging when sourcing. Confirm that the YCPZ designation indicates lead-free construction and RoHS compliance. Ensure the single-supply voltage range aligns with the target application's power constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring high linearity and wide bandwidth in signal processing chains. The adjustable VOCM pin simplifies interface design with various ADCs. Consider thermal dissipation limits when operating at elevated ambient temperatures or driving heavy loads.

Part Context

This part belongs to the ADA4939 family of ultralow distortion differential amplifiers. The '1' suffix denotes a single amplifier configuration within a 16-lead LFCSP package. The 'R2' suffix typically indicates tape and reel packaging for automated assembly processes.
