This document describes the STEVAL-CCA038V1 which is the demonstration board based on the TS4871 low-power audio amplifier. The micropackage DFN8 (dual flat no-lead 8-pin) is compact, saving board space and has good thermal dissipation. The BTL gain is set at 2 V/V and can be adapted if necessary by modifying the R1 or R2 values. On the board, the R3 and C3 component locations are empty to allow the designer to modify the input configuration from single-ended to differential mode. For differential mode, R4 must be modified. The C1 component location is also empty in order to add a low-pass filter if required. For more detailed information on calculating the component values, refer to the TS4871 datasheet.
This document provides user guidelines for the STEVAL-CCA038V1, a demonstration board designed around the TS4871 low-power audio amplifier. The board utilizes the compact DFN8 micropackage and features an operating voltage range from 2.2 V to 5.5 V.
The power supply voltage must be between 2.2 V and 5.5 V.
Shorting GND and standby puts U1 in standby mode, while shorting Voc and standby puts it in operation mode.
The amplifier delivers 1 W of output power when the voltage is 5 V.
