Introduction

The TAS5010−5112F2EVM PurePath Digitalt customer evaluation module demonstrates two integrated circuits, the TAS5010 and TAS5112ADFD from Texas Instruments. The TAS5010 is a high performance 24-bit stereo digital modulator based on Equibitt technology. This IC converts input PCM serial digital audio data to a pulse width modulated (PWM) audio data stream. The TAS5010 PWM modulator accepts I2S data with a sample rate up to 192 kHz. The TAS5010 is designed for implementation together with the TAS5112ADFD digital output stage for driving two loudspeakers in a stereo application.

The TAS5010 is pin compatible with the TAS5001 PCM−PWM modulator. The maximum sample rate for the TAS5001 is 96 kHz.

Together, the TAS5010 and one TAS5112ADFD provide the complete PurePath Digitalt conversion of a 3.3-V digital audio input stream up to 2x50 W into 6-Ωloudspeakers. The chipset is ideal for applications requiring excellent audio quality, minimum size and weight, and high power efficiency. The chipset can be used in a range of products such as micro-components systems, home theater in a box, DVD receivers, or TV sets.

The TAS5010−5112F2EVM is a complete true digital amplifier including an S/DIF receiver, I2S audio interface, volume control, interface to personal computer through the parallel port, and required control logic. The amplifier reference design is surrounded by a white line on the PCB.
