The TAS5602EVM2 evaluation module consists of a single class-D stereo audio power amplifier complete
with a small number of external components mounted on a circuit board that can be used to directly drive
speakers using a TAS3308 EVM as the input. The input connector for the TAS5602EVM2 is configured to
connect directly to the TAS3308 EVM PWM connector. The TAS5602EVM2 can be configured to drive 2
stereo BTL channels up to 20W/ch or 4 SE (single-ended) channels up to 10/ch. It is also possible to
configure the EVM to drive speakers in a 2.1 configuration with 2 channels of SE stereo and one channel
of BTL subwoofer. The user can also connect to the TAS5602EVM2 input with a ribbon cable from a
target system if desired.
This document assumes that the user has obtained a TAS3308 EVM and has set up the PurePath
Studio™ software on a test computer with USB interface. The Quick Setup Guide in the TAS3308 EVM
User's Guide (TI document SLEU093 ) describes a method to get the TAS3308 EVM up and running
efficiently.
The TAS3308 EVM outputs 6 PWM channels plus a VALID/SYNC signal. The six PWM channels are
grouped into three stereo channels named PWM1 L and R, PWM2 L and R, and PWM3 L and R. The
TAS5602EVM2 is configured to connect to PWM3, which consists of 4 output lines
