Function
Charge Pump Power Supply pin, 2.7V∼3.6V
Positive Charge Pump Capacitor Terminal 1 Pin.
Connect to CN1 with a 1.0μF capacitor that has 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.
Negative Charge Pump Capacitor Terminal 1 Pin
Connect to CP1 with a 1.0μF capacitor that has 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
Connect to VEE1 with a 1.0μF capacitor that has 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 CVSS1 pin. Non polarity capacitors can
also be used.
Negative Voltage Output Pin for Video Amplifier 1
Connect to CVSS1 with a 1.0μF capacitor that has 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 CVSS1 pin. Non polarity capacitors can
also be used.
Video Output #1 Pin
Analog Power Supply Pin, 2.7V∼3.6V
Analog Ground Pin, 0V
Test Pin
This pin should be connected to AVSS.
