160 W+160 W dual BTL class-D audio amplifier demonstration board based on the TDA7498E

The STEVAL-CCA044V1 demonstration board is designed for the TDA7498E 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 the configuration of the amplifier in order to verify all the features as single-ended or differential input, fixed gain settings.

Microswitches are also provided to enable the standby and mute functions.

Key Features

  • High output-power capability:
    • 2 x 160 W / 4 Ω at 36 V, 1 KHz, THD = 10%
    • 1 x 220 W / 4 Ω at 36 V, 1 KHz, THD = 10%
  • Wide-range, single supply operation (14 V- 36 V)
  • High efficiency (η = 85%)
  • Four selectable, fixed gain settings(23.6 dB, 29.6 dB,33.1 dB and 35.6 dB)
  • Differential inputs to minimize common-mode noise
  • Standby and mute features
  • Short-circuit and thermal overload protection
  • Externally synchronizable
  • RoHS compliant
