TAS5722L Evaluation Board
1 Introduction
To help investigate and evaluate the TAS5722L performance and capabilities, a fully populated evaluation
board has been created. This board is shown in
Figure 1 . Connected to a PC, an external power supply
(4.5 V ≤ PVDD ≤ 17 V), and a signal source, the TAS5722L Evaluation Board easily exercises the
features of the amplifier.
