1 W mini audio amplifier circuit

In this circuit requires only three components , namely IC TDA7052 , and 2 capacitor electrolyte. Actually , only with IC we are able to run this amplifier , but the sound less than the maximum. This amplifier circuit requires a minimum voltage of 3 volts and 15 volts maximum. Was 1 Watt power output with 4 Ohm impedance. See this circuit below :
