ADA4807-4ARUZ

Overview

The ADA4807-4ARUZ 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 and features an industrial temperature range of −40°C to +125°C. Key electrical specifications include a 180 MHz bandwidth (G = +1), 225 V/μs slew rate, and 3.1 nV/√Hz input voltage noise at 100 kHz. The device draws 1.0 mA quiescent current per amplifier and includes a disable pin for power management.

Feature Summary

• Combines low power consumption with high speed performance and DC precision
• Features rail-to-rail input and output capabilities for maximum dynamic range
• Includes active low disable functionality for dynamic power scaling applications

Applications

• High resolution analog-to-digital converter drivers
• Portable and battery-powered instruments and systems
• High component density data acquisition systems
• Audio signal conditioning circuits
• Active filter implementations

Procurement Notes

Verify the specific package type matches the ARUZ suffix designation as a 14-lead TSSOP. Confirm that the ordering code corresponds to the quad configuration rather than single or dual variants. Ensure the revision level aligns with current manufacturing standards. Check for any specific environmental or compliance certifications required for your target market before finalizing procurement orders.

Selection Notes

Select this component when driving multiplexed or high-throughput precision ADCs requiring low noise and fast settling. It is suitable for systems where power consumption is critical but high bandwidth is still necessary. Consider the quad topology for space-constrained designs needing multiple amplifiers in a single package. Evaluate the disable feature if dynamic power management is part of the system architecture.

Part Context

This device belongs to the ADA4807 family, which includes single (ADA4807-1) and dual (ADA4807-2) versions. All variants share identical electrical characteristics and are designed for low-noise, high-speed applications. The quad version provides four independent amplifiers in a compact 14-lead TSSOP package, offering a solution for high-density PCB layouts compared to using multiple single-channel devices.
