STMicroelectronics STEVAL-CCA042V1, Dual BTL Class-D Audio Amplifier Demonstration Board Audio Amplifier Demonstration

The STEVAL-CCA042V1 demonstration board is designed for the TDA7491HV 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 a heatsink. Jumpers on the board allow configuration of the amplifier to verify all the features as single-ended or differential inputs, fixed gain settings. Microswitches are also provided to enable the standby and mute functions20 W +20 W continuous output power at THD = 10%, RL = 8 Ω, VCC = 18 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
