ADA4891-3ARUZ

Overview

The ADA4891-3ARUZ is a triple-channel, low-cost CMOS high-speed operational amplifier with rail-to-rail output. It features a −3 dB bandwidth of 220 MHz at G = +1 and a slew rate of 170 V/μs. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, drawing 4.4 mA per amplifier. It includes dedicated power-down pins for each channel, allowing individual control. The input common-mode range extends 300 mV below the negative rail.

Feature Summary

Triple-channel architecture with independent power-down functionality
Rail-to-rail output stage maximizing dynamic range
High-speed performance with fast settling time
Extended input common-mode range extending below the negative rail

Applications

Automotive infotainment systems
Automotive driver assistance systems
Imaging applications such as CCD buffers
Active filters
Coaxial cable drivers

Procurement Notes

Verify the specific package type and temperature grade against the official Analog Devices ordering guide. Confirm that the W-grade specifications are required if tighter offset voltage limits are necessary for the application design.

Selection Notes

Select this component when multiple high-speed channels are needed in a compact footprint. The integrated power-down feature reduces system power consumption during idle states. Ensure the load requirements do not exceed the linear output current capabilities specified in the datasheet.

Part Context

This part belongs to the ADA4891 family, which includes single, dual, and quad variants. The -3 suffix indicates three amplifiers per package. The ARUZ designation specifies the 14-lead TSSOP package with an extended operating temperature range of −40°C to +125°C.

FAQ

How does the power-down feature function?

Each amplifier has a dedicated power-down pin (PD1, PD2, PD3). Driving these pins low powers down the respective amplifier, reducing quiescent current significantly.
