ADA4004-4ARZ-RL

Overview

The ADA4004-4ARZ-RL is a quad precision amplifier from Analog Devices, featuring 1.8 nV/√Hz voltage noise density and a 12 MHz gain bandwidth product. It operates on ±5 V to ±15 V supplies with a maximum supply voltage of 36 V. Key electrical parameters include a typical input offset voltage of 40 μV, maximum input bias current of 90 nA, and a slew rate of 2.7 V/μs. The device consumes 2.2 mA per amplifier and provides high open-loop gain of up to 120 dB. It is housed in a 14-Lead SOIC package.

Feature Summary

• Achieves ultralow voltage noise density of 1.8 nV/√Hz for high-fidelity signal processing
• Utilizes iPolar process technology to minimize power consumption while maintaining stability
• Provides high open-loop gain and wide bandwidth for precision control applications

Applications

• Precision instrumentation systems
• Microphone preamplifiers
• Thermocouples and RTDs signal conditioning
• Reference buffers
• Industrial control circuits

Procurement Notes

Verify the specific ordering suffix ARZ-RL corresponds to the 14-Lead SOIC_N package and reel packaging configuration. Confirm RoHS compliance status indicated by the Z suffix. Ensure the component meets the required operating temperature range of −40°C to +125°C for your specific application environment before finalizing procurement.

Selection Notes

Select this component when low noise performance is critical alongside moderate bandwidth requirements. The quad configuration allows for space-efficient designs compared to single-channel alternatives. Consider the 14-Lead SOIC package for standard surface-mount assembly processes. Evaluate the 2.2 mA per amplifier supply current against total system power budgets.
