TAS5414ATPHDRMPA

Overview

The TAS5414ATPHDRMPA is a four-channel automotive digital Class-D audio amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 6 V to 24 V and supports load impedances of 2 Ohms and 4 Ohms. The device delivers high output power, specified as 116 W x 2 at 2 Ohms or 58 W x 4 at 4 Ohms. It features a total harmonic distortion plus noise (THD+N) of 0.02% and a fixed gain of 32 dB. The component is housed in a 64-pin HTQFP package with an exposed pad and is designed for surface-mount installation. It functions reliably across an operating temperature range from -40°C to +105°C.
