general description
The LM1~9A series consists of four independent
precision voltage comparators with an offset volt-
age specification of 2 mV. max. for all four
comparators which were 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 draiA is independent of the magnitude of
the power supply voltage. These comparators also
have a unique characteristic in that 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, squarewave
and time delay generators; wide range VCO; MOS
clock timers; multivibrators and high voltage digital
logic gates. The LM 1~9A series was designed to
directly interface with TTL and CMOS. When
operated from both plus and minus power supplies,
the LM~~9A will directly interface with MOS
logic-where the low power drain of the LM~~9A
is a distinct advantage over standard comparators.
