TAS5414TDKDMQ1

Overview

The TAS5414TDKDMQ1 is a four-channel automotive digital Class-D audio amplifier designed for high-efficiency sound systems. It features single-ended analog inputs and operates within an 8 V to 22 V supply range. The device delivers up to 28 W per channel into 4 Ω loads at 14.4 V, with THD+N below 0.02%. It utilizes a patented PWM topology to reduce heat dissipation and includes integrated load diagnostics, protection circuits, and I²C configuration capabilities.

Feature Summary

• Patented pop-and-click reduction technology ensures mute transitions are smooth and free of audible artifacts.
• Integrated AM interference avoidance allows selectable switching frequencies to minimize radio noise.
• Built-in load diagnostic functions detect output shorts, open circuits, and tweeter connections.

Applications

• High-power OEM head units
• Retail head units
• PBTL amplifier modules

Procurement Notes

Verify the specific suffix TDKDMQ1 against the official datasheet to confirm package type and temperature grade. Ensure the design accounts for the required external heatsink due to thermal characteristics. Confirm I2C address settings and pull-up resistor values match system requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring four independent channels with high power density. It is suitable where reduced heat generation compared to linear amplifiers is critical. Verify that the single-ended input architecture aligns with the source signal interface. Ensure adequate thermal management solutions are integrated into the PCB layout.

Part Context

This part belongs to the TAS5414/TAS5424 family of four-channel automotive digital amplifiers. The TAS5414 variant specifically uses single-ended inputs, whereas the TAS5424 uses differential inputs. Both share similar power stages and diagnostic features but differ in input configuration for noise immunity.
