Texas Instruments TAS5753MDEVM

Overview

TAS5753MDEVM from Texas Instruments is a hardware evaluation module designed to demonstrate and validate the TAS5753MD digital-input Class-D audio amplifier IC in 2.1-channel configurations - one stereo device (bridge-tied load for left/right speakers) and one mono device (for subwoofer or full-range output), with integrated headphone/line driver, I²S interface, and real-time audio processing via PurePath Console 3 software.

For engineers reviewing the TAS5753MDEVM datasheet, TAS5753MDEVM pinout, TAS5753MDEVM application, or TAS5753MDEVM equivalent, this EVM enables rapid prototyping of high-efficiency audio systems requiring configurable multiband AGL, equalization, USB/optical/coaxial audio source integration, and end-system register-level tuning and configuration export.

Technical Context

The TAS5753MDEVM implements two physically separate TAS5753MD amplifier ICs on a single four-layer PCB: an upper stereo device (I²C address 0x56) and a lower mono device (I²C address 0x54), both receiving I²S input from the PurePath Console Motherboard (PPCMB). It supports sample rates up to 48 kHz across USB, optical, and coaxial inputs, with PVDD supply range 8–26.4 V.

Hardware features include dual speaker outputs (stereo L/R + mono), 3.5-mm headphone jack tied to the stereo device's integrated line/headphone driver, JST VHR-2N speaker connectors, five-way binding posts for PVDD/GND, and onboard RC snubber circuits for output waveform shaping. Thermal design uses dedicated bottom-layer heat escape paths and open copper areas adjacent to amplifier ICs.

FAQ

What is the TAS5753MDEVM used for?

The TAS5753MDEVM is a Texas Instruments evaluation module for the TAS5753MD Class-D audio amplifier IC. It enables engineers to evaluate 2.1-channel audio performance - including stereo playback and mono subwoofer output - using PurePath Console 3 software for real-time equalization, multiband AGL tuning, register-level configuration, and end-system integration file generation. The TAS5753MDEVM itself is not a production component but a development tool.

Does the TAS5753MDEVM require additional hardware to operate?

Yes. The TAS5753MDEVM requires the PurePath Console Motherboard (PPCMB), a compatible power supply (8–26.4 V), micro-USB cable, speakers (2 × 8 Ω for stereo, 1 × 4 Ω for mono), and a Windows PC running PurePath Console 3 software - which requires prior authorization from TI. Audio sources (USB, optical, coaxial) connect via the PPCMB, not directly to the TAS5753MDEVM.

Can the TAS5753MDEVM be used without PurePath Console 3?

No. The TAS5753MDEVM has no standalone functionality. All configuration, tuning, register access, and audio processing depend entirely on PurePath Console 3 software communicating via USB to the PPCMB, which then routes I²S and I²C signals to the TAS5753MD devices on the TAS5753MDEVM. Without PPC3 and PPCMB, the TAS5753MDEVM cannot be initialized, controlled, or tested.

What are the default I²C addresses for the amplifiers on the TAS5753MDEVM?

The stereo TAS5753MD device on the TAS5753MDEVM uses I²C address 0x56 by default; the mono TAS5753MD device uses I²C address 0x54. These addresses can be modified using external resistors (R18–R21) per the schematic, but the TAS5753MDEVM ships with these values preconfigured and expected by PurePath Console 3 during automatic detection.

Does the TAS5753MDEVM support sample rates above 48 kHz?

No. Although the PPCMB hardware supports up to 192 kHz, the TAS5753MD IC - and therefore the TAS5753MDEVM - is limited to 44.1 kHz and 48 kHz sample rates for optical and coaxial inputs, and only 48 kHz for USB input. This limitation is inherent to the TAS5753MD silicon and is enforced in PurePath Console 3; higher rates are not accepted or processed by the TAS5753MDEVM.
