Low Power Low Offset Voltage Quad Comparators
LR339
DESCRIPTION:
The LR339 consists of four independent precision voltage comparators.These were designed specifically to operate from a signal power supply over a wide range of voltage.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 LR339 also have a unique characteristic in that the input common-mode voltage range includes ground,even though operated from a single power supply voltage.
FEATURE:
z Low input biasing current: 25nA(Typ.) z Low input offset current: r5.0nA(Typ.) z Low output saturation voltage: 130mV z Output voltage compatible with TTL,CMOS
