ADA4841-2YCPZ-R7

Overview

The ADA4841-2YCPZ-R7 is a dual-channel, unity-gain stable, low power, low noise and distortion rail-to-rail output amplifier manufactured by Analog Devices. It features a quiescent current of 1.5 mA maximum per device, with a typical bandwidth of 80 MHz at a gain of +1 and a slew rate of 12 V/µs. The input voltage noise density is 2.1 nV/√Hz at 100 kHz, while the harmonic distortion reaches −105 dBc at 100 kHz with a 2 V p-p output. Operating over an industrial temperature range of −40°C to +125°C, it supports supply voltages from 2.7 V to 12 V.

Feature Summary

• Low wideband noise performance with 2.1 nV/√Hz voltage noise and 1.4 pA/√Hz current noise.
• Rail-to-rail output capability allowing signal swing within 50 mV of either supply rail.
• Integrated power-down function for significant reduction in supply current consumption.
• Capable of driving capacitive loads up to 15 pF with minimal peaking.

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required package type and reel quantity specifications. Confirm RoHS compliance status and lead finish details against the manufacturer's latest documentation. Ensure the component meets the specified industrial temperature operating range requirements for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a dual-channel configuration is required alongside low power consumption and high precision. The device is suitable for applications demanding excellent linearity and low distortion in portable or battery-operated systems. Consider the rail-to-rail output stage for maximizing dynamic range on low voltage supplies.

Part Context

This part belongs to the ADA4841 family of amplifiers, which includes single-channel (ADA4841-1) and dual-channel (ADA4841-2) variants. The YCPZ suffix indicates an 8-lead LFCSP_WD package with a wettable flange design. These amplifiers are fabricated on ADI’s second-generation XFCB process, optimizing both supply current and offset voltage performance.

Replacement Considerations

The ADA4841-1 serves as the single-channel equivalent within the same family. Other dual-channel options may require verification of pinout compatibility and electrical parameter alignment with the original datasheet specifications.

FAQ

Does the ADA4841-2 include a power-down feature?

No, the power-down function is exclusive to the ADA4841-1 variant. The ADA4841-2 does not have a dedicated power-down pin.

What is the input common-mode voltage range?

The input common-mode voltage range extends down to the negative supply rail.
