TAS6422EQDKQRQ1

Overview

The TAS6422EQDKQRQ1 is a two-channel digital-input Class-D automotive audio amplifier. It supports I2S and TDM inputs with sample rates up to 96 kHz. The device delivers 75 W into 4 Ω at 25 V BTL, or 150 W into 2 Ω in parallel mode. It operates on a 4.5 V to 26.4 V supply. Features include AEC-Q100 qualification, load dump protection up to 40 V, and I2C diagnostics for open/short detection.

Feature Summary

Supports digital audio interfaces including I2S and TDM formats.
Includes advanced load diagnostics for detecting tweeters and output faults.
Provides enhanced EMI management via spread-spectrum capabilities.
Features robust protection against load dump, over-temperature, and short circuits.

Applications

Automotive head units
Automotive external amplifiers

Procurement Notes

Verify the specific ordering suffix DKQRQ1 to confirm the reel packaging configuration. Ensure the component meets AEC-Q100 Grade 1 requirements for the target temperature range. Confirm that the HSSOP-56 package dimensions align with the PCB footprint design. Validate that the power supply voltage does not exceed the absolute maximum ratings during transient events.

Selection Notes

Select this model when a two-channel solution with high power density is required. It is suitable for applications needing integrated diagnostics to reduce manufacturing test time. Consider this part if system-level EMI constraints require spread-spectrum modulation. Verify compatibility with existing digital audio source protocols before integration.

Part Context

This component belongs to the Texas Instruments TAS6422E-Q1 family of automotive Class-D amplifiers. It shares pin compatibility with other devices in the series, such as single and four-channel variants. The device is designed to replace legacy analog input amplifiers in modern digital audio architectures.
