4.6W AUDIO POWER AMP S1A0067X01 Preliminary GENERAL DESCRIPTION The S1A0067X01 is a two channel power amplifier with 4.6W typical output on 12.0V Vcc. It ’ s typical output is 4.6W on VCC = 12.0V. There is no needs of a bootstrap-capacitor due to the use of V-PNP for a power transitory. So, it is an advantage for making a whole system. It has an additional stand-by function, the pop noise on switc hing it ’ s mute function is much reduced. The S1A0067X01 has the built-in thermal protection function with hysterisys in order to protect a blocking oscillation in a short period due to a repeated protection switching on over- heating of IC. The S1A0067X01 has a built-in output-vcc or output-gnd short protection function.
