TS4990 low voltage audio power amplifier evaluation board user guidelines

The DEMO TS4990 is an evaluation board designed for the TS4990 low power audio amplifier. The micropackage DFN8 (dual flat non leaded 8 pins) allows space saving and good thermal dissipation.

The BTL gain is set at 2V/V and can be adapted if necessary with a modification of R1 or R2 values.

On the board, R3 and C3 component locations are empty to allow you to modify the input configuration from single ended to differential. For differential mode, R4 must be modified. The C1 component location is also empty so that you can add a low pass filter if required.
