  • 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 functions

    Key Features

    • 20 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
    • RoHS compliant
