LA4183
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, V_CC = 9 V, R_L = 4 Ω
4.7 W typ./bridge amplifier, V_CC = 9 V, R_L = 8 Ω
. _{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.

Specifications
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.
