Description
Negative power supply input.
External reference input.
Reference point for REF IN.
Integrator output. Integrator capacitor connection.
Auto zero input. Auto zero capacitor connection.
Analog input buffer output. Integrator resistor connection.
Reference capacitor input. Reference capacitor negative connection.
Reference capacitor input. Reference capacitor positive connection.
Analog input. Analog input negative connection.
Analog input. Analog input positive connection.
Positive power supply input.
Digit drive output. Most Significant Digit (MSD)
Binary Coded Decimal (BCD) output. Least Significant Bit (LSB)
BCD output.
BCD output.
BCD output. Most Significant Bit (MSB)
Digit drive output.
Digit drive output.
Digit drive output.
Digit drive output. Least Significant Digit (LSD)
Busy output. At the beginning of the signal-integration phase, BUSY goes High and
remains High until the first clock pulse after the integrator zero crossing.
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.
Strobe output. The STROBE output pulses low in the center of the digit drive outputs.
Over range output. A logic High indicates that the analog input exceeds the full scale input
range.
Under range output. A logic High indicates that the analog input is less than 9% of the full
scale input range.
