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
