CLOCK IN
POLARITY
Clock input. Conversion clock connection.
Polarity output. A positive input is indicated by a logic
high output. The polarity output is valid at the
beginning of the reference integrate phase and
remains valid until determined during the next
conversion.

Digital logic reference input.
Run/Hold input. When at a logic high, conversions are
performed continuously. A logic low holds the current
data as long as the low condition exists.
