2.3 W 2-Channel AF Power Amplifier for Radio
Cassette Players
Features
.
Built-in 2 channels enabling use in stereo and bridge
amplifier (BTL) applications.
.
High-output:
2.3 W typ./channel, VCC =9 V, RL =4
4.7 W typ./bridge amplifier, VCC =9 V, RL =8
.
Low switching distortion at high frequencies.
.
Minimum number of external parts required: 9 pcs. min.
(Stereo/bridge).
.
Small shock noise at the time of power supply ON/OFF due
to built-in muting circuit.
.
Good ripple rejection 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.

SANYO : DIP12F
Note:
In general applications, heat generated in the DIP 12-pin
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.
