STMicroelectronics STEVAL-CCA028V1 Demonstration Board
STMicroelectronics STEVAL-CCA028V1 Class-D Audio Amplifier Demonstration Board is designed for the TDA7491P high-power dual BTL class-D audio amplifier. Due to its high efficiency, the device is assembled in the PSSO36 (slug-down) package and can dissipate heat without any heatsink.
Jumpers on the board allow configuring the amplifier to verify all the features as single-ended or differential inputs and fixed gain settings. Microswitches are also provided to enable the standby and mute functions.
Features
- 10W +10W continuous output power at THD = 10%, RL = 6Ω, VCC = 11V
- 9.5W +9.5W continuous output power at THD = 10%, RL = 8Ω, VCC = 12V
- 5V to 18V wide single-supply operation
- High efficiency (η= 90%)
- Four selectable, fixed gain settings (20dB, 26dB, 30dB, and 32dB)
- Differential inputs to minimize common-mode noise
- Filterless operation
- Standby and mute features
- Short-circuit and thermal overload protections
- Externally synchronizable
- RoHS compliant
