Negative rail for display drivers.
Input: When HI, turns on most significant decimal point.
Output: Pulled HI when result count exceeds
±
19,999.
Input: Second most significant decimal point on when HI.
Output: Pulled HI when result count is less than
±
1000.
Input: When floating, ADC operates in the free-run mode.
When pulled HI, the last displayed reading is held. When
pulled LO, the result counter contents aren shown
inincrementing during the deintegrate phase of cycle.
Output:
Negative-going edge occurs when the data latches
are updated. Can be used for converter status signal.
Negative power supply terminal.
Positive power supply terminal and positive rail for display
drivers.
Input to integrator amplifier.
Output of integrator amplifier.
Input: When LO, continuity flag on the display is OFF.
When HI, continuity flag is ON.
Output: HI when voltage between inputs is less than +200
mV. LO when voltage between inputs is more than +200
mV.
Sets common-mode voltage of 3.2V below V
+
for DE,
10X, etc. Can be used as preregulator for external
reference.
Positive side of external reference capacitor.
Negative side of external reference capacitor.
Output of buffer amplifier.
Negative input voltage terminal.
Positive input voltage terminal.
