ADA4004-1ARJZ-RL

Overview

The ADA4004-1ARJZ-RL is a single-channel precision operational amplifier manufactured by Analog Devices. It operates within a supply voltage range of ±5 V to ±15 V and supports an operating temperature from -40°C to +125°C. The device features a maximum offset voltage of 125 µV, a maximum input bias current of 90 nA, and a gain bandwidth product of 12 MHz. It consumes 1.7 mA per amplifier in supply current and utilizes a 5-Lead SOT-23 package.

Feature Summary

Procurement Notes

Verify the specific ordering suffix RL indicates reel packaging when sourcing this component. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the selected variant matches the required 5-Lead SOT-23 footprint for PCB layout compatibility. Cross-reference the full part number against official distributor catalogs to confirm availability and authenticity.

Selection Notes

Select this amplifier for applications requiring ultralow noise and high precision over a wide temperature range. The single-channel configuration suits designs needing one high-performance op amp. Consider the 5-Lead SOT-23 package for space-constrained layouts. Evaluate the 12 MHz bandwidth against system requirements to ensure adequate speed without unnecessary power consumption.

Part Context

This component belongs to the ADA4004 series of precision amplifiers, which includes dual (ADA4004-2) and quad (ADA4004-4) variants. All members share the same core technology and electrical characteristics but differ in channel count and package options. The series is designed for high-precision analog signal conditioning tasks across industrial and medical fields.

Replacement Considerations

Direct substitutes include other models within the ADA4004 family such as the ADA4004-2 or ADA4004-4 if additional channels are needed. Verify pinout compatibility and thermal resistance specifications before replacing components in existing designs.
