Function
FC
Frequency Control Input for Internal Oscillator
and Charge Pump. With FC = Open (ADM660)
or connected to GND (ADM8660), f
CP
= 25 kHz;
with FC = V+, f
CP
= 120 kHz
Positive Charge-Pump Capacitor T erminal.
Power Supply Ground.
Negative Charge-Pump Capacitor T erminal.
Output, Negative Voltage.
Low Voltage Operation Input. Connect to GND
when input voltage is less than 3.5 V. Above
3.5 V, LV may be connected to GND or left
unconnected.
ADM660: Oscillator Control Input. OSC is
connected to an internal 15 pF capacitor. An
external capacitor may be connected to slow the
oscillator. An external oscillator may also be
used to overdrive OSC. T he charge-pump
frequency is equal to 1/2 the oscillator frequency.
ADM8660: Shutdown Control Input. T his in-
put, when high, is used to disable the charge
pump thereby reducing the power consumption.
Positive Power Supply Input.
