IS31AP2111-ZLS1-TR

Overview

The IS31AP2111-ZLS1-TR is a digital audio amplifier manufactured by Lumissil Microsystems. It features a Class-D output stage capable of delivering 20W per channel into an 8Ω load when powered by a 24V supply. The device utilizes a digital I2S interface for audio input and integrates advanced processing functions including volume control, 20-band speaker equalization, audio mixing, 3D surround sound, and Dynamic Range Control (DRC). These parameters are programmable via an I2C interface. The amplifier operates within a voltage range of 4.5V to 24V and supports differential inputs.

Feature Summary

• Integrates 20-band speaker equalization and dynamic range control for advanced audio processing
• Features a robust anti-pop circuit ensuring pop-free operation during power-on sequences
• Includes comprehensive protection circuits against short circuits and over-temperature conditions

Applications

• Driving stereo speakers in automotive infotainment systems
• High-fidelity home audio amplification setups
• Portable high-power audio devices requiring efficient thermal management

Procurement Notes

Verify the specific suffix ZLS1-TR against official Lumissil documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with I2S audio sources and I2C control buses. Confirm moisture sensitivity handling requirements prior to assembly. Cross-reference the part number with current datasheets to validate pinout and electrical characteristics against system design constraints.

Selection Notes

Select this component for applications requiring integrated digital audio processing alongside high-efficiency power amplification. The Class-D topology eliminates the need for external heat sinks in many configurations. Verify that the system design accommodates the 24V supply requirement and I2S digital interface. Consider the eTSSOP-24 package dimensions for PCB layout constraints.

Part Context

This device belongs to Lumissil's line of digital audio amplifiers designed for high-performance audio applications. It combines power amplification with digital signal processing capabilities, distinguishing it from standard analog Class-D amplifiers. The integration of EQ and DRC reduces the need for external DSP components, simplifying the overall system architecture.
