ADA4004-2ARZ-RL

Overview

The ADA4004-2ARZ-RL is a dual precision operational amplifier from Analog Devices, featuring a voltage noise density of 1.8 nV/√Hz and a gain bandwidth product of 12 MHz. It operates within ±5 V to ±15 V supplies with a maximum supply voltage of 36 V. The device offers an input offset voltage of 40 μV typical and 125 μV maximum at ±15 V, along with an input bias current of 90 nA maximum. Designed on the iPolar process, it consumes 1.7 mA per amplifier and functions across a temperature range of −40°C to +125°C.

Feature Summary

• Features very low voltage noise density of 1.8 nV/√Hz for high signal integrity.
• Utilizes the high-performance iPolar process to reduce power consumption and footprint size.
• Provides high open-loop gain of 120 dB for precise amplification.
• Operates stably over a wide temperature range from −40°C to +125°C.

Applications

• Precision instrumentation
• Microphone preamplifiers
• Thermocouples and RTDs
• Industrial control systems

Procurement Notes

Verify that the ordering suffix -RL corresponds to the tape-and-reel packaging option as specified in the official Analog Devices Ordering Guide. Confirm the package type matches the 8-Lead SOIC_N (R-8) designation. Ensure compliance with RoHS standards indicated by the Z suffix. Cross-reference the specific part number against the manufacturer's current documentation to validate availability and revision status before procurement.

Selection Notes

Select this component when low noise and high precision are required in dual-channel applications. The 12 MHz bandwidth supports high-speed filtering needs. Consider the 8-Lead SOIC package for board space constraints compared to larger packages. Verify that the ±5 V to ±15 V operating range aligns with the system power supply design requirements.

Part Context

This device belongs to the ADA4004 series, which includes single (ADA4004-1), dual (ADA4004-2), and quad (ADA4004-4) configurations. All variants share the same core technology and performance characteristics, differing primarily in channel count and package options. The series is designed for applications requiring low noise and high accuracy.

Replacement Considerations

The ADA4004-2ARMZ serves as a pin-compatible alternative in the 8-Lead MSOP package. Other members of the ADA4004 family offer similar electrical specifications but vary in channel count.
