ADA4004-1ARZ-R7

Overview

The ADA4004-1ARZ-R7 is a single-channel precision operational amplifier manufactured by Analog Devices Inc. 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 supply current of 2.4 mA per amplifier. Key electrical specifications include an input offset voltage of 40 μV (maximum 125 μV at 25°C), an input bias current of 90 nA, and a common-mode rejection ratio of 113 dB. It is housed in an 8-Lead SOIC package.

Feature Summary

• Achieves ultra-low voltage noise density of 1.8 nV/√Hz utilizing high-performance iPolar process technology.
• Provides high open-loop gain of up to 120 dB for precise signal amplification.
• Operates reliably across a wide temperature range from -40°C to +125°C.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'R7' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the RoHS compliant status indicated by the 'Z' suffix meets environmental regulations for the target deployment region. Ensure the 8-Lead SOIC package dimensions align with the printed circuit board layout constraints.

Selection Notes

Select this component when low noise performance is critical for signal integrity in precision applications. The 12 MHz bandwidth supports high-speed filtering requirements while maintaining stability. Consider the ±5 V to ±15 V operating range to ensure compatibility with available power rails in the system design.

Part Context

This part belongs to the ADA4004 series, which includes dual and quad variants offering similar low-noise characteristics. The series utilizes the iPolar process to reduce power consumption and footprint size compared to previous generations. It serves as a direct replacement for older precision op-amps requiring sub-nanovolt noise performance.
