STMicroelectronics STEVAL-CCA044V1 Demonstration Board

STMicroelectronics STEVAL-CCA044V1 Class-D Audio Amplifier Demonstration Board is designed for the TDA7498E high-power dual BTL class-D audio amplifier. Due to its high efficiency, the device assembled in the PSSO36 (slug-down) package can dissipate heat without a heatsink.

Jumpers on the board allow the configuration of the amplifier to verify all the features as single-ended or differential input and fixed gain settings. Microswitches are also provided to enable the standby and mute functions.

Features

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