STMicroelectronics STEVAL-CCA028V1, Class-D Audio Amplifier Demonstration Board Audio Amplifier Demonstration Board for

The STEVAL-CCA028V1 demonstration board is designed for the TDA7491P high-power dual BTL class-D audio amplifier. Thanks to its high efficiency, the device assembled in the PSSO36 (slug-down) package is capable of dissipating heat without any heatsink. Jumpers on the board allow configuring the amplifier in order to verify all the features as single-ended or differential inputs, fixed gain settings. Microswitches are also provided to enable the standby and mute functions.10 W +10 W continuous output power at THD = 10%, RL= 6 Ω, VCC = 11 V 9.5 W + 9.5 W continuous output power at THD = 10%, RL= 8 Ω, VCC = 12 V Wide-range single-supply operation (5-18 V) High efficiency (η = 90 %) Four selectable, fixed gain settings (20 dB, 26 dB, 30 dB and 32 dB) Differential inputs to minimize common-mode noise Filterless operation Standby and mute features Short-circuit and thermal overload protections Externally synchronizable
