ADA4807-2ACPZ-R7

Overview

The ADA4807-2ACPZ-R7 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 with a quiescent current of 1 mA per amplifier. Key electrical parameters include a 3.1 nV/√Hz input voltage noise density, ±125 μV maximum input offset voltage, and a 96 dB common-mode rejection ratio. It is housed in a compact 10-lead LFCSP package.

Feature Summary

• Rail-to-rail input and output capability for maximum dynamic range
• Low power operation with 1 mA quiescent current per channel
• High-speed performance with 180 MHz bandwidth and fast settling time
• Ultra-low input voltage noise density of 3.1 nV/√Hz

Applications

• High resolution analog-to-digital converter (ADC) drivers
• Portable and battery-powered instruments and systems
• High component density data acquisition systems
• Audio signal conditioning
• Active filters

Procurement Notes

Verify the specific ordering suffix ACPZ-R7 corresponds to the 10-lead LFCSP-WD package and reel packaging configuration. Confirm that the DISABLE pin functionality aligns with system power-down requirements. Ensure thermal management strategies account for the junction temperature limits specified in the datasheet under maximum power dissipation conditions.

Selection Notes

Select this component when both low noise and high speed are critical requirements within a single supply or split supply architecture. The dual-channel configuration reduces board space compared to single amplifiers. Consider the 10-lead LFCSP package for applications requiring high pin density and efficient heat dissipation through the exposed pad.

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 electrical characteristics but differ in channel count and package options. The ADA4807-2 specifically provides two independent amplifiers in one package, offering a balance between performance and footprint efficiency.

Replacement Considerations

Direct functional replacements within the same family include ADA4807-2ARMZ-R7 (MSOP-8 package). Other packages such as SC70 or SOT-23 are available for the single-channel variant but require circuit redesign due to pinout differences.
