(1) Control amplifier (pin 1, pin 7, pin 8) The differential amplifier’s positive input is pin 1, its negative input pin 8, and its output pin 7.
Set the input bias voltage so that the pin 7 voltage is VCC / 2.
The amplification degree is determined by the external constant.
Optical disc ICs VCO with sensitivity adjustment function BA7042 The BA7042 is a monolithic IC comprising a VCO (voltage controlled oscillator) with sensitivity adjusting capabilities.
The oscillation frequency can be set with an external constant, and is controlled according to the control voltage.
The BA7042 can be used to produce high-modulation-factor FM signals by superimposing its control voltage with AC signals, and to configure a PLL circuit just by attaching a frequency divider and a phase comparator.
