ADA4004-1ARZ-RL

Overview

The ADA4004-1ARZ-RL is a single-channel precision operational amplifier manufactured by Analog Devices Inc. It features a voltage noise density of 1.8 nV/√Hz and operates within a supply voltage range of ±5 V to ±15 V (total 10 V to 30 V). The device offers a gain-bandwidth product of 12 MHz, a slew rate of 2.7 V/µs, and an input offset voltage maximum of 140 µV at 25°C. It consumes 2.0 mA per amplifier and is housed in an 8-Lead SOIC package.

Feature Summary

• Achieves ultralow voltage noise density of 1.8 nV/√Hz with a low 6 Hz 1/f noise corner frequency.
• Utilizes the high-performance iPolar process for reduced power consumption and improved stability.
• Provides high open-loop gain and wide bandwidth suitable for precision signal conditioning.

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 format required for automated assembly processes. Confirm the specific package option R-8 matches the footprint requirements of the target printed circuit board design before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring low noise performance combined with moderate speed capabilities. Ensure the application environment remains within the specified operating temperature range of −40°C to +125°C. Verify that the supply voltage does not exceed the absolute maximum ratings to maintain device reliability.

Part Context

This part belongs to the ADA4004 series of precision amplifiers, which includes dual and quad variants. The series is designed for applications demanding high accuracy and low power consumption. The single-channel configuration allows for flexible layout options in space-constrained designs compared to multi-channel alternatives.
