NTE943, NTE943M, & NTE943SM
Integrated Circuit
Low Power, Low Offset, Dual Voltage Comparator
Description:
The NTE943, NTE943M, and NTE943SM consist of two independent precision voltage comparators
with an offset voltage speciication as low as 2.0mV max for two comparators which were designed
specifically to operate from a single power supply over a wid range of voltages. Operation from split
power supplies is also possible and the low power supply current drain is independent of the magni-
tude of the power supply voltage. These comparators alos have a unique characteristic in that the
input common–mode voltage range includesground, even though operated from a single powe sup-
ply voltage.
Application areas include limit comparators, simple analog to digital converters; pulse, squarewave
and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital
logic gates. These devices are designed to directly interface with TTL and CMOS. When operated
from both plus and minus power supplies they will directly interface with MOS logic where their low
power drain is a distinct advantage over standard comparators.
