High-Voltage Reverse-Input-Capable 4–20mA
Current Loop Protector
Note 2: All devices are 100% production tested at T
A
= +25NC, unless otherwise noted. Limits over the -40NC to +85NC operating
temperature range are guaranteed by design.
Note 3: Turn-on time and turn-off time are defined as the difference in the time between when the output voltage crosses 10% and
90% of the final output voltage.
Note 4: Input current source can support voltage up to +40V (absolute maximum). Current reaction time is defined as the settling
time of the output current after a fault event.
