Voltage Comparator
Voltage Comparator
General Description
• The TCI LM393 consist of two independent voltage
comparator, designed specifically to operate from a single
power supply over a wide voltage range.
• The LM393 is available in standard DIP-8, SOP-8
and TSSOP-8 packages.
.
Features Applications
• Single or dual supply operation
• Wide operating supply range
CC=2V ~ 36V or ±1 ~ ±18V)
