Input Range and Protection
The full-scale analog input voltage is a product of the
reference voltage. For the devices, the input is unipolar
in the range of:
In external reference mode, drive VREFIO with a 3.0V to
4.25V source, resulting in a full-scale input range of
3.662V to 5.188V, respectively.
All analog inputs are fault-protected up to ±20mA. The
devices include an input clamping circuit that activates
when the input voltage at the analog input is above
(VAVDD + 300mV) or below -300mV. The clamp circuit
remains high impedance while the input signal is within
the range of 0V to +VAVDD and draws little to no cur-
rent. However, when the input signal exceeds the range
of 0V to +VAVDD, the clamps begin to turn on.
Consequently, to obtain the highest accuracy, ensure
that the input voltage does not exceed the range of 0V
to +VAVDD.
To make use of the input clamps, connect a resistor
(RS) between the analog input and the voltage source
to limit the voltage at the analog input so that the fault
current into the devices does not exceed ±20mA. Note
that the voltage at the analog input pin limits to approxi-
mately 7V during a fault condition so the following
equation can be used to calculate the value of RS:
where VFAULT_MAX is the maximum voltage that the
source produces during a fault condition.
