ADA4004-1ARJZ-R7

Overview

The ADA4004-1ARJZ-R7 is a single-channel precision operational amplifier manufactured by Analog Devices. It features a voltage noise density of 1.8 nV/√Hz and a gain bandwidth product of 12 MHz. The device operates on supply voltages ranging from ±5 V to ±15 V with a maximum total supply of 36 V. Key electrical specifications include an input offset voltage of 40 μV, an input bias current of 90 nA, and a slew rate of 2.7 V/μs. It consumes 1.7 mA per amplifier and is housed in a 5-lead SOT-23 package.

Feature Summary

• Achieves ultra-low voltage noise density of 1.8 nV/√Hz with a low 6 Hz 1/f noise corner frequency.
• Designed on the high-performance iPolar process for reduced power consumption and improved stability.
• Provides high open-loop gain of 120 dB and wide common-mode rejection ratio.

Applications

• Precision instrumentation
• Microphone preamplifiers
• Thermocouples and RTDs signal conditioning
• Reference buffers

Procurement Notes

Verify the specific ordering suffix R7 corresponds to the reel packaging format required for automated assembly processes. Confirm that the RoHS compliant designation matches environmental regulations applicable to the target manufacturing region. Ensure the component temperature range meets the operational requirements of the final system environment.

Selection Notes

Select this component when low noise performance is critical alongside moderate bandwidth requirements. The single-channel configuration in a compact SOT-23 package suits space-constrained designs. Verify that the supply voltage range aligns with the available power rails in the circuit architecture.

Part Context

This part belongs to the ADA4004 series, which includes dual and quad variants offering similar electrical characteristics across different channel counts. The series utilizes the iPolar process technology to deliver high precision and low power consumption. It serves as a solution for applications requiring high accuracy in analog signal processing chains.

Replacement Considerations

Check for availability of other suffixes such as ARJZ-R2 or ARJZ-RL if different tape and reel quantities are needed. Consider the ADA4004-2ARMZ or ADA4004-2ARZ if dual-channel functionality is required instead of a single unit.
