NJM2901C / NJM2901CA
SINGLE-SUPPLY QUAD COMPARATOR
■ GENERAL DESCRIPTION
The NJM2901C / NJM2901CA consist of four independent voltage
comparators that are designed specifically to operate from a single power
supply over a wide range of voltages. Operation from split power supplies
is also possible and the low power supply current drain is independent of
the magnitude of the power supply voltage. The NJM2901C / NJM2901CA
has a unique characteristic: the input common-mode voltage range
includes ground, even though operated from a single power supply voltage.
Application areas include limit comparators, simple analog-to-digital
converters; pulse, square-wave and time delay generators; wide range
VCO; MOS clock timers; multi-vibrators and high voltage digital logic gates.
The NJM2901C /NJM2901CA were designed to directly interface with TTL
and MOS. When operated from both plus and minus power supplies, the
NJM2901C will directly interface with MOS logic where their low power
drain is a distinct advantage over standard comparators.
