... Whe the DC voltage to be applied to pin (5) is set at approximately 1.1V, TR1, 2 are turned ON and ALC is turned ON. For the rectifier circuit recommended to use the voltage doubler rectifirer which is excellent in compression ratio. For the sets ALC width can be made wider even at the time of decreased voltages. LA4160 characteristics recommended to use a germanium diode so that the CC No.870– ...

... However, this pin can be safely used as the power supply for a built-in capacitor microphne. 5. Recording Muting The recording muting at the time of recording by use of the built-in microphone is enabled by applying voltage to feedback pin (3) of the power amplifier.

... In case of using in a radio-cassette recorder, the IC and the bar antenna must be arranged sufficiently distant from each other to avoid the radiation of higher harmonic component at the time of output saturation of the power amplifier. 7. Pin-to-pin short causes breakdown and deterioration. 8. Load short causes breakdown and deterioration of both preamplifier and power amplifier. LA4160 No.870–8/11 ...
