PIN/FUNCTION
Function
Negative Charge Pump Capacitor Terminal Pin
Connect to CP with a 1.0μF capacitor that should have the low ESR
1
CN
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
2
CP
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.
De-emphasis Mode Pin (Internal pull-down pin)
3
DEM
I
When at “H”, the de-emphasis filter is available.
Master Clock Input Pin
4
MCLK
I
An external TTL clock should be input on this pin.

Ground Pin2
Negative Voltage Output Pin
Connect to VSS2 with a 1.0μF capacitor that should have the low ESR
16
(Equivalent
Series Resistance)
over all temperature range. When this
VEE
O
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.
No.
