ADA4930-1YCPZ-R2

Overview

The ADA4930-1YCPZ-R2 is a single-channel, ultralow noise differential amplifier designed for driving low voltage ADCs. It operates on a single 3.3 V or 5 V supply with a quiescent current of approximately 34 mA per amplifier. The device features a small-signal bandwidth of 1.35 GHz and a slew rate of 3400 V/μs at 5 V. Input voltage noise is 1.2 nV/√Hz, with a typical input offset voltage of 0.5 mV. It provides adjustable output common-mode voltage and supports differential-to-differential or single-ended-to-differential configurations.

Feature Summary

• Ultralow input voltage noise density of 1.2 nV/√Hz
• Internal common-mode feedback loop ensures exceptional output balance
• Adjustable output common-mode voltage via dedicated VOCM pin
• Single-supply operation compatible with 3.3 V and 5 V systems

Applications

• ADC drivers for high-performance data acquisition
• Single-ended-to-differential signal conversion
• IF and baseband gain blocks in communication systems
• Differential buffers and line drivers

Procurement Notes

Verify the specific suffix R2 against the manufacturer's latest ordering guide to confirm packaging type and reel specifications. Ensure the component matches the 16-lead LFCSP package dimensions. Confirm RoHS compliance status and humidity sensitivity handling requirements prior to assembly. Cross-reference the datasheet revision to ensure all electrical parameters align with your design specifications.

Selection Notes

Select this component when driving 1.8 V high-performance ADCs requiring resolutions up to 14 bits. It is suitable for applications demanding high speed and low distortion from DC to 70 MHz. Consider the 1.35 GHz bandwidth and 3400 V/μs slew rate for wideband signal processing. The adjustable VOCM allows precise matching to ADC input ranges without external level shifting circuits.

Part Context

This part belongs to the ADA4930 family of ultralow noise differential amplifiers fabricated using Analog Devices' proprietary silicon-germanium complementary bipolar process. The ADA4930-1 variant is packaged in a 16-lead, 3 mm × 3 mm LFCSP. The family is optimized for PCB layout to minimize distortion and facilitate high-speed analog signal chain design.
