ADAU1592ACPZ-RL7

Overview

The ADAU1592ACPZ-RL7 is a two-channel, bridge-tied load (BTL) switching audio power amplifier with an integrated Sigma-Delta modulator. It accepts analog input signals and generates a switching output to drive speakers directly. The device operates from supply voltages ranging from 9 V to 18 V for the power stage, while the analog modulator and digital logic operate from a 3.3 V supply. Key electrical parameters include a maximum output power of 24 W at 10% THD+N into a 4 Ω load, a total harmonic distortion plus noise of 0.005%, and a dynamic range of 101 dB.

Feature Summary

• Integrates a stereo modulator and power stage with EMI-optimized modulation.
• Features on/off-mute pop-noise suppression for clean audio transitions.
• Includes comprehensive short-circuit and overtemperature protection circuits.

Applications

• Flat panel televisions
• PC audio systems
• Mini-components

Procurement Notes

Verify the specific package type against the datasheet, as the ADAU1592 family includes both LFCSP-48 and TQFP-48 options. Confirm that the component matches the Rev B specifications regarding thermal resistance and pin configurations. Ensure compatibility with the required PVDD operating voltage range of 9 V to 18 V during system design validation.

Selection Notes

Select this component for applications requiring high-efficiency Class-D amplification without external filter components. The integrated Sigma-Delta modulator simplifies PCB layout by reducing external connections. Consider the available PGA gain settings (0 dB to 18 dB) when designing the input signal chain to match the desired full-scale output level.

Part Context

This part belongs to the Analog Devices ADAU1592 series of Class-D audio power amplifiers. The series is characterized by its ability to drive speakers directly using pulse density modulation. The ACPZ suffix indicates the LFCSP-48 package variant, which provides specific thermal dissipation characteristics compared to other package types in the same product family.
