Description The TDA7492E is a dual BTL class-D audio amplifier with single power supply designed for home audio applications. The device is housed in a 36-pin PowerSSO Features ■ Wide-range single-supply operation (7 - 26 V) ■ Possible output configurations: − 2 x PBTL − 1 x Parallel BTL ■ BTL output capabilities (VCC = 26 V): − 61 W + 61 W, 4 Ω, THD 1% − 79 W + 79 W, 4 Ω, THD 10% − 44 W + 44 W, 6 Ω, THD 1% − 57 W + 57 W, 6 Ω, THD 10% − 34 W + 34 W, 8 Ω, THD 1% − 44 W + 44 W, 8 Ω, THD 10% ■ Parallel BTL output capabilities (VCC = 26 V): − 86 W, 3 Ω, THD 1% − 110 W, 3 Ω, THD 10% ■ High efficiency ■ Four selectable, fixed-gain settings of nominally 20.8 dB, 26.8 dB, 30 dB and 32.8 dB ■ Differential inputs minimize common-mode noise ■ Standby, mute and play operating modes ■ Short-circuit protection ■ Output power limited by PLIMIT function ■ Detection of shorted output pins during startup
