Overview

The TAS2505IRGER is a low-power digital input mono Class-D speaker amplifier with support for 2W output into 4-ohm loads. It features an integrated mono headphone amplifier and a programmable digital audio processor for on-chip equalization and bass boost.

Why Choose This Part

This IC integrates a programmable miniDSP for custom EQ and filtering, reducing the processing load on the host MCU. It supports a wide range of sample rates from 9kHz to 96kHz and features robust protection against thermal overload and output shorts.

Applications

Portable Consumer Electronics
Ideal for handheld devices requiring integrated speaker and headphone outputs with minimal power consumption.
IoT Voice Assistants
Suitable for smart speakers and voice-enabled IoT nodes needing clear mono audio playback and digital volume control.
Diagnostic Alarms
Provides reliable audio feedback in industrial equipment thanks to its load diagnostic functions and short-circuit protection.
