Function
Rch Negative Analog Input Pin
Rch Positive Analog Input Pin
Lch Negative Analog Input Pin
Lch Positive Analog Input Pin
Negative Voltage Output Pin
Connect to VSS2 with a 1.0μF capacitor that should have the low ESR (Equivalent
Series Resistance)
over all temperature range. When this capacitor has the polarity,
the positive polarity pin should be connected to the VSS2 pin. Non polarity capacitors
can also be used.
Negative Charge Pump Capacitor Terminal Pin
Connect to CP with a 1.0μF capacitor that should have the low ESR (Equivalent Series
Resistance) over all temperature range. When this capacitor has the polarity, the
positive polarity pin should be connected to the CP pin. Non polarity capacitors can
also be used.
Positive Charge Pump Capacitor Terminal Pin
Connect to CN with a 1.0μF capacitor that should have the low ESR (Equivalent Series
Resistance) over all temperature range. When this capacitor has the polarity, the
positive polarity pin should be connected to the CP pin. Non polarity capacitors can
also be used.
Charge Pump Ground Pin , 0V
Charge Pump Power Supply Pin: 3.13V ~ 3.47V
Normally connected to VSS2 with a 0.1μF ceramic capacitor in parallel with a 4.7μF
electrolytic cap.
Interrupt Pin for Video Blanking
Normally connected to VVD1(3.3V) through 10kΩ resistor externally.
