ADA4807-4ARUZ-R7

Overview

The ADA4807-4ARUZ-R7 is a quad, low noise, rail-to-rail input and output, voltage feedback amplifier from Analog Devices Inc. It operates within a supply range of 2.7 V to 11 V. Key electrical specifications include an 180 MHz bandwidth (G = +1), a 225 V/μs slew rate, and a quiescent current of 1.0 mA per amplifier at ±5 V. The device features 3.1 nV/√Hz input voltage noise and supports industrial temperature ranges from -40°C to +125°C.

Feature Summary

• Combines low power consumption with high speed performance and DC precision for data acquisition systems.
• Features rail-to-rail input and output capabilities across the full supply voltage range.
• Includes active low disable functionality for dynamic power scaling in battery-powered applications.

Applications

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

Procurement Notes

Verify the specific package type and reel quantity associated with the -R7 suffix against the manufacturer's official ordering guide. Confirm that the pinout matches the 14-lead TSSOP configuration detailed in the datasheet. Ensure environmental compliance requirements align with the product specifications before finalizing procurement.

Selection Notes

Select this component when driving multiplexed or high-throughput precision SAR and delta-sigma ADCs requiring low noise and fast settling. The quad configuration is suitable for high-density designs where space is limited. Consider the disable pin utility for power management in portable devices requiring extended battery life.

Part Context

This part belongs to the ADA4807 family, which includes single (ADA4807-1) and dual (ADA4807-2) variants. The quad version provides four independent amplifiers in a single package, offering a solution for applications needing multiple signal conditioning channels without increasing board footprint significantly compared to discrete solutions.

Replacement Considerations
