www.ti.com Quick Setup Guide 2 Quick Setup Guide This section describes the TAS5162DKD6EVM board in regards to power supplies and system interfaces. The section provides information regarding handling and unpacking, absolute operating conditions, and a description of the factory default switch and jumper configuration. This chapter provides a step-by-step guide to configuring the TAS5162DKD6EVM for device evaluation. 2.

www.ti.com Quick Setup Guide Note: 2.4 The length of power supply cable must be minimized. Increasing length of PSU cable is equal to increasing the distortion for the amplifier at high output levels and low frequencies. Speaker Connection CAUTION Both positive and negative speaker outputs are floating and may not be connected to ground (e.g. through an oscilloscope). 2.5 GUI Software Installation The TAS5518 GUI provides easy control of all registers in the TAS5518.
