2.3 W 2-Channel AF Power Amplifier
Features
.
Built-in 2 channels enabling use in stereo and bridge
amplifier applications.
.
High output: 2.3 W/channel, VCC =9 V, RL =4 , and
4.7 W/bridge, RL =8 .
.
Minimum number of external parts required : 9 pcs. min.
(Stereo/bridge).
.
Small pop noise at the time of power supply ON/OFF due to
built-in muting circuit.
.
Good ripple rejection ratio due to built-in ripple filter.
.
Soft tone at the time of output saturation.
.
Good channel separation.
.
Voltage gain fixed at 45 dB (Bridge: 51 dB). Variable
voltage gain available with external resistor added.
.
Easy to design radiator fin.

SANYO : DIP12F
Note) In general applications, heat generated in this package
can be radiated through the Cu-foiled area of the printed
circuit board, but since power dissipation Pd may be
increased depending on the supply voltage and load
conditions, it is recommended to use a fin additionally.
