STEVAL-CCA029V1

STEVAL-CCA029V1 5 W + 5 W class-D audio amplifier demonstration board based on the TDA7491LP Data brief Features ■ 5 W + 5 W continuous output power at THD = 10%, RL = 8 Ω, VCC = 9 V ■ 5 W + 5 W continuous output power at THD = 10%, RL = 4 Ω, VCC = 6.5 V ■ Power supply voltage range: 5 V to 14 V ■ Number of channels: 2 BTL (bridge tied load) stereo ■ Load impedance: 4 Ω to 8 Ω ■ Gain settings: 20 dB, 26 dB, 30 dB, 32 dB ■ Undervoltage protection (UVP): 4 V ■ External synchronization ■ RoHS compliant Description The STEVAL-CCA029V1 demonstration board is designed for the evaluation of the TDA7491LP dual BTL class-D audio amplifier. Due to its high efficiency, the device, assembled in the PSSO36 (slug-down) package, is capable of dissipating heat without any heatsink. Jumpers on the board allow the configuration of the amplifier in order 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.
