SLASEG6B May 2018 – June 2020 TAS3251
The TAS3251 device integrates four main building blocks into a single cohesive device that maximizes sound quality, flexibility, and ease of use. These include:
The device requires three power supplies for proper operation. A 3.3 V rail for the low voltage circuitry and DAC, a 12 V rail for the amplifier gate-drive, and PVDD which is required to provide power to the output stage of the audio amplifier. The operating range for these supplies is shown in the Recommended Operating Conditions.
The communication and control interface for the device uses I2C. A speaker amplifier fault output is also provided to notify a system controller of the occurrence of an overtemperature, overcurrent or undervoltage event.
The µCDSP audio processing core is pre-programmed with configurable DSP programs. The PurePath™ Console 3 software with the TAS3251 App available on TI.com provides the tools to control and tune the pre-programmed audio process flows.
