10 W + 10 W class-D audio amplifier demonstration board based on the TDA7491P

下载数据摘要

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
