I/O Function
Negative Charge Pump Capacitor Terminal Pin
Connect to CP with a 1.0μF capacitor that should have the low ESR
I
(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
I
(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.
I
Soft Mute Enable Pin (Internal pull down: 100kΩ)
“H”: Enable, “L”: Disable
I
Master Clock Input Pin
An external TTL clock should be input on this pin.

O
(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.
Note: All input pins except for the CN pin should not be left floating.
