ADA4841-1YRZ-RL

Overview

The ADA4841-1YRZ-RL is a single-channel, unity-gain stable operational amplifier from Analog Devices. It features low power consumption with a maximum quiescent current of 1.5 mA per amplifier and operates within a supply voltage range of 2.7 V to 12 V. The device provides a wideband voltage noise of 2.1 nV/√Hz and an input current noise of 1.4 pA/√Hz at 100 kHz. It offers a gain bandwidth product of 80 MHz and a slew rate of 12 V/µs. The output swings to within 50 mV of either rail, and the input common-mode range extends down to the negative supply.

Feature Summary

• Rail-to-rail output capability with minimal headroom loss
• Low power operation with integrated power-down function
• High precision with low offset voltage and drift
• Excellent linearity for high-resolution signal processing

Applications

• Battery-powered instrumentation
• 16-bit PulSAR ADC drivers
• Low power, low noise signal processing

Procurement Notes

Verify the specific package type and reel quantity against the official ordering guide before procurement. Confirm that the Y suffix indicates lead-free RoHS compliant finish. Ensure the operating temperature range meets your application requirements as specified in the datasheet absolute maximum ratings.

Selection Notes

Select this component when low noise and low distortion are critical alongside power efficiency. It is suitable for driving high-resolution ADCs such as the AD7685/AD7686. Consider the power-down feature if battery life extension is required. Verify capacitive load drive capabilities if interfacing with long cables or sample-and-hold circuits.

Part Context

This part belongs to the ADA4841 family of low power, low noise amplifiers. The -1 designation indicates a single-channel configuration, while the YRZ suffix specifies the 8-lead SOIC package with RoHS compliance. The -RL suffix denotes tape and reel packaging. It shares performance characteristics with the dual-channel ADA4841-2 variant.

FAQ

Does the ADA4841-1 include a power-down feature?

Yes, the ADA4841-1 includes a dedicated power-down pin that allows the user to reduce the supply current significantly when the amplifier is not in use.

What is the input common-mode voltage range?

The input common-mode voltage range extends down to the negative supply rail, allowing for full differential input swing in single-supply applications.
