Vývojová sada pro analogové obvody STEVAL-CCA042V1 Demonstrační deska dual BTL audio zesilovače třídy D TDA7491HV Audio

The STEVAL-CCA042V1 demonstration board is designed for the TDA7491HV 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 configuration of the amplifier 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

• 20 W +20 W continuous output power at THD = 10%, RL = 8 Ω, VCC = 18 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
