HYSTERESIS
The Hysteresis control voltage varies the comparator hysteresis from 0 mV to 10 mV, for a change
from –5.2 V to –2.2 V at the Hysteresis control pin. Normally converted to –5.2 V.
The most positive reference voltage for the internal resistor ladder.
One of two analog input pins. Both analog input pins should be connected together.
One of two analog ground pins. Both analog ground pins should be connected together.
Noninverted input of the differential encode input. This pin is driven in conjunction with
ENCODE
. Data is latched on the rising edge of the ENCODE signal.
Inverted input of the differential encode input. This pin is driven in conjunction with ENCODE.
One of two analog ground pins. Both analog ground pins should be connected together.
One of two analog input pins. Both analog inputs should be connected together.
The most negative reference voltage for the internal resistor ladder.
The midpoint tap on the internal resistor ladder.
One of four digital ground pins. All digital ground pins should be connected together.
One of two negative digital supply pins (nominally –5.2 V). Both digital supply pins should be con-
nected together.
Digital data output.
Digital data output.
One of four digital ground pins. All digital ground pins should be connected together.
One of two negative analog supply pins (nominally –5.2 V). Both analog supply pins should be con-
nected together.
One of four digital ground pins. All digital ground pins should be connected together.
Digital data output.
Digital data output.
Overflow data output. Logic high indicates an input overvoltage (V
IN
> +V
REF
) if OVERFLOW
INHIBIT is enabled (overflow enabled, –5.2 V). See OVERFLOW INHIBIT.
One of two negative digital supply pins (nominally –5.2 V). Both digital supply pins should be
connected together.
