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
