integration phase when a positive input voltage is being integrated
and is low when a negative input voltage is being integrated. A high-
to-low transition on CMPTR signals the processor that the De-
integrate phase is completed. CMPTR is undefined during the auto-
zero phase. It should be monitored to time the integrator zero phase.
Input. Digital ground.
Input. Power supply positive connection.
Input. Negative power supply converter capacitor (+) connection.
Input. Negative power supply converter capacitor (-) connection.
Output. Negative power supply converter output and reservoir
capacitor connection. This output can be used to power other
devices in the circuit requiring a negative bias voltage.
Oscillator control input. The negative power supply converter
normally runs at a frequency of 100 kHz. The converter oscillator
frequency can be slowed down (to reduce quiescent current) by
connecting an external capacitor between this pin and V
