3 Description
The LM339-MIL device consists of four independent
precision voltage comparators with an offset voltage
specification as low as 2 mV maximum for all four
comparators. These comparators 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 drain 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 they are operated from a single power supply
voltage.
The LM339-MIL device was designed to directly
interface with TTL and CMOS. When operated from
both plus and minus power supplies, the device
directly interfaces with MOS logic where the lowpower
drain of the LM339-MIL is a distinct advantage
over standard comparators.
