ADA4004-4ACPZ-RL

Overview

The ADA4004-4ACPZ-RL is a quad precision operational amplifier manufactured by Analog Devices Inc. It features a voltage noise density of 1.8 nV/√Hz and an input offset voltage of 40 μV typical, with a maximum drift of 0.7 μV/°C. The device operates on the iPolar™ process, providing a gain bandwidth product of 12 MHz and a slew rate of 2.7 V/μs. It supports supply voltages from ±5 V to ±15 V (up to 36 V total) and consumes 1.7 mA per amplifier. The component is housed in a 16-lead LFCSP_WQ package and functions within a temperature range of −40°C to +125°C.

Feature Summary

• Achieves ultralow voltage noise density of 1.8 nV/√Hz with a low 6 Hz 1/f noise corner frequency.
• Utilizes high-performance iPolar™ process technology for reduced power consumption and improved stability.
• Provides high open-loop gain of 120 dB and wide bandwidth of 12 MHz for precision signal processing.

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required reel quantity and packaging format. Confirm RoHS compliance status as indicated by the 'Z' suffix. Ensure the specific LFCSP_WQ thermal pad connection requirements are met during assembly to maintain specified thermal resistance values.

Selection Notes

Select this component when multiple channels of low-noise amplification are required in a compact footprint. The quad configuration reduces board space compared to single-channel alternatives. Verify that the ±5 V to ±15 V operating range aligns with the system power supply constraints.

Part Context

This part belongs to the ADA4004 series, which includes single (ADA4004-1), dual (ADA4004-2), and quad (ADA4004-4) variants. All members share identical electrical characteristics but differ in channel count and package options. The series is designed for applications requiring high precision and low noise across a wide temperature range.

Replacement Considerations

Direct functional substitutes include ADA4004-4ARZ and ADA4004-4ACPZ-R7. These parts share the same electrical specifications but may differ in package type or reel packaging format. Verify pin compatibility and thermal performance before substitution.

FAQ

What is the recommended connection for the exposed pad in the LFCSP package?

It is recommended that the exposed paddle be connected to V– (negative supply).

Does the ADA4004-4 exhibit phase reversal upon overdrive?

No, the device is designed to prevent phase reversal even when the input signal exceeds the common-mode range.
