TAS5414ATPHDRPA

Overview

The TAS5414ATPHDRPA is a four-channel digital audio amplifier from Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 6 V to 24 V and supports load impedances of 2 Ohms or 4 Ohms. The device delivers up to 116 W per channel into a 2-Ohm load (stereo mode) or 58 W per channel into a 4-Ohm load (quad mode). It features a Class-D architecture with a total harmonic distortion plus noise (THD+N) of 0.02%. The component is housed in an HTQFP-64 package and functions across an operating temperature range of -40°C to +105°C.

Feature Summary

• Four-channel digital audio amplification capability for automotive head units and external modules
• Class-D topology ensuring high efficiency and low thermal output
• Supports both stereo and quad-channel configurations with variable power output based on load impedance
• Integrated digital interface for direct connection to audio processors
