GENERAL DESCRIPTION
12- SIPH- B
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.
