  • 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.

    Key Features

    • 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
    • RoHS compliant
