Overview
The TAS5717PHPR, manufactured by Texas Instruments, is a 10-W stereo digital audio power amplifier designed for driving stereo bridge-tied speakers. This device is part of the TAS5717/TAS5719 family, which offers efficient Class-D operation and integrated cap-free headphone amplifiers. It supports a wide range of input data and data rates, making it versatile for various audio applications. The amplifier operates with a PWM carrier between 384 kHz and 352 kHz, depending on the input sample rate, and features oversampling combined with a fourth-order noise shaper to provide a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.
