ADA4807-2ACPZ-R2

Overview

The ADA4807-2ACPZ-R2 is a dual-channel, low noise, rail-to-rail input and output voltage feedback amplifier manufactured by Analog Devices Inc. It combines high speed performance with DC precision, featuring an 180 MHz bandwidth and a 225 V/μs slew rate. The device operates on supply voltages ranging from 2.7 V to 11 V, drawing only 1.0 mA of quiescent current per amplifier. Key electrical specifications include a maximum input offset voltage of ±125 μV, an input voltage noise density of 3.1 nV/√Hz at 100 kHz, and a common-mode rejection ratio of 96 dB. It is housed in a compact 10-lead LFCSP package.

Feature Summary

• Rail-to-rail input and output capabilities allow for maximum dynamic range operation across the full supply voltage range.
• Integrated active-low disable pin enables power-down mode with microamp-level current consumption for energy efficiency.
• Low distortion performance supports high-fidelity signal processing in demanding audio and data acquisition applications.

Applications

• High resolution analog-to-digital converter (ADC) drivers
• Portable and battery-powered instruments and systems
• Audio signal conditioning

Procurement Notes

Verify the specific ordering suffix R2 against official documentation to confirm packaging details, as suffixes define reel or tube quantities. Ensure the component matches the required 10-lead LFCSP form factor and industrial temperature range specifications before integration into the design.

Selection Notes

Select this component when both low noise and high speed are critical requirements within a single channel. The dual configuration offers space savings compared to using two single amplifiers. Consider the available disable functionality if system power management requires periodic shutdown of unused channels.

Part Context

This part belongs to the ADA4807 family, which includes single (ADA4807-1), dual (ADA4807-2), and quad (ADA4807-4) variants. All members share identical core electrical characteristics but differ in channel count and physical package options such as MSOP, LFCSP, TSSOP, SOT-23, and SC70.

Replacement Considerations

Direct functional substitutes within the same family include ADA4807-2ACPZ-R7 and ADA4807-2ARMZ. Verify that any replacement maintains the same 10-lead LFCSP footprint and electrical parameters if pin compatibility is required.
