TAS2505ATRGERQ1

Overview

The Texas Instruments TAS2505ATRGERQ1 is a mono Class-D speaker amplifier designed for automotive applications. It supports both digital and analog inputs, delivering up to 2.6 W output power into a 4 Ω load at 5.5 V with 10% THD+N. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and features an integrated LDO. It includes programmable digital audio processing such as bass boost, treble, and EQ. The component is housed in a 24-pin VQFN package with wettable flanks.

Feature Summary

• Supports both digital I2S interfaces and analog line inputs for flexible system integration
• Includes embedded DSP capabilities for bass boost, treble adjustment, and parametric equalization
• Features comprehensive load diagnostics including short circuit and over-temperature protection
• AEC-Q100 qualified for automotive environments with extended temperature range operation

Applications

• Automotive instrument clusters
• Emergency call (eCall) systems
• Telematics units

Procurement Notes

Verify the specific suffix 'ATRGE' against the manufacturer's official orderable part list to confirm tape-and-reel packaging and moisture sensitivity levels. Ensure the procurement channel provides traceability documentation required for AEC-Q100 qualified components. Confirm that the delivered units match the exact grade and revision specified in the current datasheet.

Selection Notes

Select this component when a single-channel amplifier with integrated DSP is required for automotive displays or communication modules. It is suitable for designs needing direct digital audio input to eliminate external DACs. Consider the 24-pin VQFN package constraints and thermal requirements for high-power operation in confined spaces.

Part Context

This part belongs to the TAS2505-Q1 family of automotive Class-D amplifiers. It shares core functionality with other variants in the series but is distinguished by its specific ordering suffix indicating automated test configurations and reel packaging. It serves as a specialized solution for compact automotive audio subsystems requiring robust diagnostic features.
