Monolithic Linear IC
LA4145
0.6 to 0.9 W AF Power Amplifier
for Radio Cassette Recorders
Features
. The LA4145 is especially suited for use in cassette tape
recorder, radio-cassette, recorder, stereo cassette player
. applications.
0.6 W typ/VCC = 6.0 V, RL = 8 Ω, THD = 10%
0.9 W typ/VCC = 6.0 V, RL = 4 Ω, THD = 10%
. Minimum number of external parts required
. Soft clip
. Small pop noise at VCC ON/OFF mode
. Voltage gain fixed at 50 dB.
An external resistor can be connected to reduce this value.
