12 AOUTL
Lch Analog Output Pin
O
When power down, outputs VSS(0V, typ).
Negative Voltage Output Pin
Connect to VSS1 with a 1.0μF capacitor which is low ESR (Equivalent
13 VEE
O
Series Resistance) over all temperature range. When this capacitor has the
polarity, the positive polarity pin must be connected to the VSS1 pin. Non
polarity capacitors can also be used.
Negative Charge Pump Capacitor Terminal Pin
Connect to CP with a 1.0μF capacitor which is low ESR (Equivalent Series
14 CN
I
Resistance) over all temperature range. When this capacitor has the polarity,
the positive polarity pin must 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 which is low ESR (Equivalent Series
15 CP
I
Resistance) over all temperature range. When this capacitor has the polarity,
the positive polarity pin must be connected to the CP pin. Non polarity
capacitors can also be used.
16 VSS1
