Description
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

Connect the TAS3308 EVM to TAS5602EVM2 Place the TAS3308 EVM and TAS5602EVM2 at the same height and let the 40 pin connector on each board face each other. Push them together carefully until they make a solid connection 9V Supply... - Page 4 TAS3308 EVM and use the Pure Path Studio GDE to select the correct Mux to route the audio signal to the PWM3 output. 3. Turn on the power supply for the TAS5602EVM2. LED2 next to the PVCC jack on the TAS5602EVM2 should be lit. Audio power should be reaching the speakers (loads) at this time.
