4 / 16 page TDA7294S 4/16 Note (*): MUSIC POWER CONCEPT MUSIC POWER is the maximal power which the amplifier is capable of producing across the rated load resistance (regardless of non lin- earity) 1 sec after the application of a sinusoidal input signal of frequency 1KHz. Note (**): Tested with optimized Application Board (see fig. 3) Note (***): Limited by the max. allowable current. Note (***): For supply voltage ≥35V, The device could be demaged in short circuit conditions when the input signal is applied eN Total Input Noise A = curve f = 20Hz to 20kHz 1 µV 25 µV fL, fH Frequency Response (-3dB) PO = 1W 20Hz to 20kHz Ri Input Resistance 100 k Ω SVR Supply Voltage Rejection f = 100Hz; Vripple = 0.5Vrms 60 75 dB TS Thermal Shutdown 150 °C STAND-BY FUNCTION (Ref: -VS or GND) VST on Stand-by on Threshold 1.5 V VST off Stand-by off Threshold 3.5 V ATTst-by Stand-by Attenuation 70 90 dB Iq st-by Quiescent Current @ Stand-by 1 3 mA MUTE FUNCTION (Ref: -VS or GND) VMon Mute on Threshold 1.5 V VMoff Mute off Threshold 3.5 V ATTmute Mute Attenuation 60 80 dB CLIP DETECTOR Duty Duty Cycle ( pin 5) THD = 1%; RL = 10K Ω to 5V 10 % THD = 10%; RL = 10K Ω to 5V 30 40 50 % ICLEAK PO = 50W 3 µA Table 5.
