ADA4000-4ARZ

Overview

The ADA4000-4ARZ is a quad, low-cost, precision JFET input operational amplifier manufactured by Analog Devices Inc. It features a gain bandwidth product of 5 MHz and a slew rate of 20 V/µs. The device operates on supply voltages ranging from ±4 V to ±18 V with a typical supply current of 1.65 mA per amplifier. Key electrical characteristics include a maximum offset voltage of 1.70 mV, a maximum input bias current of 40 pA, and a voltage noise density of 16 nV/√Hz at 1 kHz. It is housed in a 14-Lead SOIC_N (R-14) package.

Feature Summary

JFET input structure providing high input impedance and very low bias current
Unity gain stable operation with wide bandwidth and fast settling time
Input common-mode voltage range includes the positive power supply rail

Applications

Driving analog-to-digital converter inputs
Buffering digital-to-analog converter outputs
High-side signal conditioning
Instrumentation-quality photodiode amplification
Fast precision filters including phase-locked loop filters

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel quantity. The 'ARZ' designation indicates the 14-Lead SOIC_N package and RoHS compliance. Confirm that the required packaging format matches the available options such as tube or reel variants before finalizing procurement.

Selection Notes

Select this component for applications requiring precision signal processing with minimal input current loading. The inclusion of the positive supply rail in the common-mode range makes it suitable for single-supply or high-side sensing configurations. Ensure the load capacitance requirements are managed to prevent oscillation in unity gain setups.

Part Context

This part belongs to the ADA4000 series of low-cost, precision JFET input operational amplifiers. The series includes single-channel (ADA4000-1), dual-channel (ADA4000-2), and quad-channel (ADA4000-4) versions. All variants share identical electrical specifications but differ in channel count and pinout configuration within their respective packages.
