• On Products Compliant to MIL-PRF-38535,
All Parameters Are Tested Unless Otherwise
Noted. On All Other Products, Production
Processing Does Not Necessarily Include Testing
of All Parameters.
2 Applications
• Chemical or Gas Sensor
• Desktop PC
• Motor Control: AC Induction
• Weigh Scale
3 Description
The device consist of two independent voltage
comparators that are designed to operate from a
single power supply over a wide range of voltages.
Operation from dual supplies also is possible as long
as the difference between the two supplies is 2 V to
36 V, and V
CC
is at least 1.5 V more positive than the
input common-mode voltage. Current drain is
independent of the supply voltage. The outputs can
be connected to other open-collector outputs to
achieve wired-AND relationships.
The LM193-MIL device is characterized for operation
from −55°C to +125°C.
