Analog Input. Power supply connection for digital logic and
serial port. Proper power-up sequencing is critical, see the
Applications section.
Input. The negative power supply converter normally runs at
a frequency of 100kHz. This frequency can be slowed down to
reduce quiescent current by connecting an external capacitor
between this pin and V
+
. (See Typical Characteristics).
Analog Input. Power supply connection for the A/D analog
section and DC-DC converter. Proper power-up sequencing is
critical, see the Applications section.
Analog Input. Storage capacitor positive connection for the
DC/DC converter.
Analog Input. Ground connection for DC/DC converter.
Analog Input. Storage capacitor negative connection for the
DC/DC converter.
No connect. Do not connect any signal to these pins.
