Integrator output. Integrator capacitor connection.
Negative power supply input (TC500/500A only).
Auto-zero input. The Auto-zero capacitor connection.
Buffer output. The Integrator capacitor connection.
This pin is grounded in most applications. It is recommended that
ACOM and the input common pin (V
analog common mode range (CMR).
Input. Negative reference capacitor connection.
Input. Positive reference capacitor connection.
Input. External voltage reference (–) connection.
Input. External voltage reference (+) connection.
Negative analog input.
Positive analog input.
Input. Converter phase control MSB. (See input B.)
Input. Converter phase control LSB. The states of A, B place the
TC5xx in one of four required phases. A conversion is complete
when all four phases have been executed:

CMPTR OUT
Zero crossing comparator output. CMPTR is HIGH during the
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
Deintegrate phase is completed. CMPTR is undefined during the
Auto-Zero phase. It should be monitored to time the Integrator Zero
phase (see text).
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 100kHz. The converter oscillator frequency can
be slowed down (to reduce quiescent current) by connecting an
external capacitor between this pin and V

istics Curves).
