The STEVAL-CCA029V1 is a demonstration board from STMicroelectronics for evaluating the TDA7491LP dual BTL class-D audio amplifier. The data brief lists the board's main features: 5 W + 5 W continuous output power, a 5 V to 14 V supply range, two BTL stereo channels, 4 Ω to 8 Ω load impedance, selectable gain settings and undervoltage protection.
The document explains that the device is assembled in the PSSO36 (slug-down) package and can dissipate heat without a heatsink. Jumpers on the board allow configuration for single-ended or differential inputs and fixed gain settings, and microswitches enable the standby and mute functions. A circuit schematic and a revision history table are included.
