LR339_15 Datasheet, PDF (1/6 Pages) Leshan Radio Company – Low input biasing current: 25nA(Typ.)

LESHAN RADIO COMPANY, LTD.
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
