TAS5414CTPHD

Overview

The TAS5414CTPHD is a Class-D audio amplifier manufactured by Texas Instruments, housed in an HTQFP-64 package. It features four-channel stereo output with single-ended analog inputs. The device operates on a supply voltage ranging from 6 V to 24 V and supports a minimum load impedance of 4 Ohms. Key electrical specifications include a maximum output power of 23 W and 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.

Feature Summary

• Four-channel Class-D architecture for multi-speaker configurations
• Single-ended analog input interface
• Integrated protection mechanisms including thermal and short-circuit safeguards
• Supports hardware mute and shutdown control

Applications

• General-purpose audio amplification systems
• Multi-channel speaker setups requiring low distortion
• Embedded audio modules operating within standard voltage ranges

Procurement Notes

Verify the specific suffix CPHD against the official datasheet to confirm pinout and packaging details. Ensure the application design accommodates the specified 6 V to 24 V supply range and 4 Ohm minimum load impedance. Confirm that the HTQFP-64 package dimensions align with the PCB layout requirements. Check for any updated lifecycle status or alternative recommendations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a four-channel solution with single-ended inputs is required. It is suitable for applications needing 23 W output into 4 Ohm loads. Consider the HTQFP-64 package for board space constraints. Verify that the operating temperature range of -40°C to +105°C meets environmental demands. Compare against other TAS5414 variants if differential inputs or automotive qualification are necessary.

Part Context

This part belongs to the TAS5414C series of Class-D audio amplifiers. It shares architectural similarities with other members like the TAS5414A and TAS5414B but differs in input type and specific electrical ratings. The series is designed for high-efficiency audio reproduction. The C variant specifically denotes single-ended analog inputs, distinguishing it from differential input models in the same family.

Replacement Considerations

Check for TAS5414ATPHD or TAS5414BTPHD if different input types are acceptable. Verify pin-to-pin compatibility with existing designs. Consult the manufacturer's latest documentation for any recommended new design alternatives.
