Analog Input ESD Protection
Figure 52 shows the input structure on any of the analog input
pins that provides ESD protection. The diode provides the main
ESD protection for the analog inputs. Care must be taken that
the analog input signal never drops below the GND rail by
more than 200 mV. If this happens, the diode will become
forward-biased and start conducting current into the substrate.
The 4 pF capacitor is the typical pin capacitance and the resistor
is a lumped component made up of the on resistance of the
multiplexer switch.

AIN Interrupts
The measured results from the AIN inputs are compared with
the AIN V
HIGH
(greater than comparison) and V
LOW
(less than or
equal to comparison) limits. An interrupt occurs if the AIN
inputs exceed or equal the limit registers. These voltage limits
are stored in on-chip registers. Note that the limit registers are 8
bits long while the AIN conversion result is 10 bits long. If the
voltage limits are not masked out, then any out-of-limit com-
parisons generate flags that are stored in the Interrupt Status 1
register (Address = 00h) and one or more out-of-limit results
will cause the INT/INT output to pull either high or low
depending on the output polarity setting. It is good design
practice to mask out interrupts for channels that are of no
concern to the application. Figure 53 shows the interrupt
structure for the ADT7516/ ADT7517/ADT7519. It gives a
block diagram representation of how the various measurement
channels affect the INT/INT pin.
Upper deadband has been reached. DAC output is not capable of increasing.
