Application example
Operation notes
(1)
Thermal-shut-down circuit is built in. In case
IC chip temperature rise to 175
(typ.),
thermal-shut-down circuit operates and
muted the output current. Next time IC chip
temperature falls below 150
(typ.), the
driver blocks start.
(2)
In case supply voltage falls below 3.8V(typ.),
output current is muted. Next time supply
voltage rises to 4.0V(typ.), the driver block
start.
(3)
Bias-pin (pin 27) should be pulled up more
than 1.3V. In case bias-pin voltage is pulled
down under 0.7V (typ.), output current is
muted.
(4)
Mute operation is caused by Thermal-shut-
down, Stand-by, decrease of bias pin voltage
or decrease of supply voltage. When mute is
done, output voltage becomes internal
reference voltage (about PowVcc/2).
(5)
One of the standby terminals low or open,
muted channel circuit (include opamps)
shutdown.
