STEVAL-CCA044V1

STEVAL-CCA044V1 160 W + 160 W dual BTL class-D audio amplifier demonstration board based on the TDA7498E Data brief Features ■ High output-power capability: – 2 x 160 W / 4 Ω at 36 V, 1 KHz, THD = 10% – 1 x 220 W / 4 Ω at 36 V, 1 KHz, THD = 10% ■ Wide-range, single supply operation (14 V36 V) ■ High efficiency (η = 85%) ■ Four selectable, fixed gain settings (23.6 dB, 29.6 dB,33.1 dB and 35.6 dB) ■ Differential inputs to minimize common-mode noise ■ Standby and mute features ■ Short-circuit and thermal overload protection ■ Externally synchronizable ■ RoHS compliant Description The STEVAL-CCA044V1 demonstration board is designed for the TDA7498E 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 the configuration of the amplifier in order to verify all the features as single-ended or differential input, fixed gain settings. Microswitches are also provided to enable the standby and mute functions.
