1 Overview
The TAS5717/19EVM evaluation module demonstrates the TAS5717 and TAS5719 devices from Texas
Instruments. The TAS5717/19 combines a high-performance PWM processor with a class-D audio power
amplifier. This EVM can be configured with two bridge-tied loads (BTL) (2.0). For detailed information
about the TAS5717 and TAS5719 devices, review the (device data sheet SLOS655). For the remainder of
the User's Guide, these devices are referred to as the TAS5717/19EVM. The Pulse Width Modulator
(PWM) is based on TI's Equibit™ technology. The TAS5717/19 has additional audio processing features
like 3D, Bass Boost and 2-band DRC. The TAS5717/19 can also drive a headphone load through TI's
DirectPath(TM) headphone amplifier.
The EVM software, with its graphic user interface (GUI), facilitates evaluation by providing access to the
TAS5717/19EVM registers through a USB port. See the Using the EVM Software section for further
details.
