MAX1302
Figure 8 illustrates the software-selectable differential
analog input voltage range that produces a valid digital
output. Each analog input differential pair can be inde-
pendently programmed to one of three differential input
ranges by setting the R[2:0] control bits with DIF/SGL = 1.
Regardless of the specified input voltage range and
whether the channel is selected, each analog input is
±6V fault tolerant. The analog input fault protection is
active whether the device is unpowered or powered.
Any voltage beyond FSR, but within the ±6V fault-toler-
ant range, applied to an analog input results in a full-
scale output voltage for that channel.
Clamping diodes with breakdown thresholds in excess
of 6V protect the MAX1302 analog inputs during ESD
and other transient events (Figure 6). The clamping
diodes do not conduct during normal device operation,
nor do they limit the current during such transients.
When operating in an environment with the potential for
high-energy voltage and/or current transients, protect
the MAX1302 externally.
