ADA4841-2YCPZ-RL

Overview

The ADA4841-2YCPZ-RL 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 maximum quiescent current of 1.5 mA per amplifier with a typical bandwidth of 80 MHz at a gain of +1 V/V. The device exhibits a wideband voltage noise of 2.1 nV/√Hz and current noise of 1.4 pA/√Hz at 100 kHz. It supports a supply voltage range from 2.7 V to 12 V and operates within an industrial temperature range of −40°C to +125°C.

Feature Summary

• Low power consumption with a maximum quiescent current of 1.5 mA per amplifier channel
• Rail-to-rail output capability allowing signal swing to within 50 mV of either supply rail
• Low noise performance including 2.1 nV/√Hz wideband voltage noise and 7 nV/√Hz at 10 Hz
• Capable of driving capacitive loads up to 10 pF with minimal peaking

Applications

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

Procurement Notes

Verify the specific ordering suffix YCPZ-RL against the manufacturer's official documentation to confirm the package type and reel specifications. Ensure compatibility with the required operating temperature range and supply voltage constraints for the target application design.

Selection Notes

Select this component for applications requiring high precision and low noise in portable or battery-operated systems. The dual-channel configuration allows for efficient space utilization in high channel count designs while maintaining low power dissipation and excellent linearity for driving high-resolution analog-to-digital converters.

Part Context

This part belongs to the ADA4841 family of amplifiers, which are designed using ADI's second-generation XFCB process. The series includes single-channel (ADA4841-1) and dual-channel (ADA4841-2) variants, all sharing similar electrical characteristics optimized for low power and high precision signal conditioning tasks.

Replacement Considerations

The ADA4841-1 serves as the single-channel counterpart within the same product family. Designers should verify pinout compatibility and ensure that the dual-channel architecture meets the system requirements before substituting with other operational amplifiers.
