TAS5414CTPHDR

Overview

The TAS5414CTPHDR is a four-channel Class-D audio amplifier from Texas Instruments, housed in an HTQFP-64 package. It operates on a single-ended analog input and supports supply voltages between 6 V and 24 V. The device delivers up to 23 W of output power into a 4 Ohm load with a total harmonic distortion plus noise (THD+N) of 0.02%. It functions within a temperature range of -40°C to +105°C and includes shutdown capabilities for power management.

Feature Summary

• Four-channel digital power amplification with single-ended analog inputs
• Patented pop-and-click reduction technology utilizing soft muting and gain ramp control
• Integrated I2C serial interface for device configuration and channel gain adjustment
• Comprehensive protection mechanisms including short-circuit, over-temperature, and load diagnostic functions

Applications

• Automotive head units requiring multi-channel audio processing
• External automotive amplifier modules
• High-fidelity consumer audio systems
• Portable audio devices with high voltage requirements

Procurement Notes

Verify the specific suffix 'HDR' against the manufacturer's official datasheet to confirm tape-and-reel packaging and moisture sensitivity levels. Ensure the component meets AEC-Q100 standards if intended for automotive applications, as commercial variants may lack this certification. Cross-reference the exact part number with the latest TI documentation to avoid confusion with similar models like the TAS5414ATPHDR or TAS5414CTPHD.

Selection Notes

Select this model when single-ended analog inputs are preferred over differential signals. It is suitable for designs requiring flexible channel configurations and robust protection features. Consider the HTQFP-64 package size for PCB layout constraints. Verify that the required output power and load impedance align with the 4 Ohm and 2 Ohm specifications provided in the technical data.

Part Context

This component belongs to the TAS5414C series of four-channel automotive digital amplifiers. It shares core architecture with the TAS5424C-Q1 but differs in input type, using single-ended rather than differential inputs. The series is designed for high efficiency and low distortion in demanding audio environments.

Replacement Considerations

The TAS5414CTPHD is a tray-packaged variant of the same core device. For automotive qualification, verify if the TAS5414ATPHDRMQ1 or other AEC-Q100 certified equivalents meet the specific thermal and reliability requirements of the design.
