ADA4004-4ACPZ-R7

Overview

The ADA4004-4ACPZ-R7 is a quad precision operational amplifier manufactured by Analog Devices Inc. It features a voltage noise density of 1.8 nV/√Hz and an offset voltage of 40 μV typical, with a maximum drift of 0.7 μV/°C. The device offers a gain bandwidth product of 12 MHz and a slew rate of 2.7 V/μs. It operates on supply voltages ranging from ±5 V to ±15 V, consuming 1.7 mA per amplifier. Packaged in a 16-lead LFCSP_WQ (CP-16-23), it supports operation from -40°C to +125°C.

Feature Summary

• Utilizes iPolar™ process technology for low noise and power consumption
• Features very low input bias current of 90 nA maximum
• Provides high open-loop gain of 120 dB
• Designed for small footprint size and layout flexibility

Applications

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

Procurement Notes

Verify the specific package option CP-16-23 corresponds to the 16-Lead LFCSP_WQ format. Confirm RoHS compliance status indicated by the Z suffix. Ensure the ordering suffix matches the required reel quantity or tape configuration for manufacturing integration. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity.

Selection Notes

Select this component when multiple low-noise channels are required within a compact surface-mount footprint. The 12 MHz bandwidth suits applications needing moderate speed with high DC accuracy. Consider the ±5 V to ±15 V operating range for compatibility with standard dual-supply rails. Evaluate thermal resistance characteristics if multiple amplifiers operate simultaneously at elevated temperatures.

Part Context

This device belongs to the ADA4004 series, which includes single (ADA4004-1) and dual (ADA4004-2) channel variants. All members share the same core electrical specifications and iPolar™ process technology. The quad configuration allows designers to implement complex multi-stage filtering or signal conditioning circuits without increasing board space significantly compared to discrete solutions.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the ADA4004-4ARZ (14-Lead SOIC_N). Other series members like the ADA4004-1 or ADA4004-2 offer identical performance but with fewer channels.
