Features

■ High output-power capability: –2 5 W / 6 Ω at 16 V, 1 KHz,THD = 10% –2 0 W / 8 Ω at 18 V, 1 KHz, THD = 10% ■ Wide-range , single supply operation (5 V- 18 V) ■ High efficiency (η = 90%) ■ Four selectable, fixed gain settings (20 dB, 26 dB, 30 dB and 32 dB) ■ Differential input to minimize common-mode noise ■ Standby and mute features ■ Short-circuit and thermal overload protection ■ Externally synchronizable ■ RoHS compliant

Description

The STEVAL-CCA043V1 demonstration board is designed for the TDA7491MV mono BTL class-D power 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 the configuration of the amplifier in order to verify all the features as single-ended or differential input, fixed gain settings. Microswiches are also provided to enable the standby and mute functions.
