ADA4004-4ACPZ-R2

Overview

The ADA4004-4ACPZ-R2 is a quad precision amplifier from Analog Devices, utilizing the iPolar™ process for low noise and power consumption. It features a voltage noise density of 1.8 nV/√Hz at 1 kHz and a gain-bandwidth product of 12 MHz. The device operates on supply voltages ranging from ±5 V to ±15 V (total 10 V to 36 V) with a maximum supply current of 2.4 mA per amplifier. Key electrical characteristics include an input offset voltage of 40 μV typical, an input bias current of 90 nA maximum, and a slew rate of 2.7 V/μs. It is housed in a 16-lead LFCSP_WQ package.

Feature Summary

• Achieves very low voltage noise density of 1.8 nV/√Hz using high-performance iPolar™ trench-isolation technology.
• Provides wide bandwidth of 12 MHz combined with low supply current consumption of approximately 1.7 mA per amplifier.
• Features high open-loop gain of 120 dB and low input offset voltage drift of 0.7 μV/°C over temperature.

Applications

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

Procurement Notes

Verify that the specific suffix R2 corresponds to the required reel packaging format as listed in the official ordering guide. Confirm the component meets RoHS compliance standards indicated by the Z suffix. Ensure the 16-lead LFCSP_WQ package option matches the intended PCB footprint design constraints.

Selection Notes

Select this component when multiple channels are required within a compact form factor. The quad configuration allows for space-efficient designs compared to single-channel alternatives. Consider the ±5 V to ±15 V operating range and the specific noise requirements relative to other members of the ADA4004 series.

Part Context

This part belongs to the ADA4004-1/ADA4004-2/ADA4004-4 family of precision amplifiers. The quad version integrates four independent operational amplifiers into a single package. The series is designed to offer improvements in speed, stability, and footprint size through novel design techniques on the iPolar™ process.
