LND339

DATA SHEET www.DataSheet4U.com LND339 Quadruple Differential Comparators GENERAL DESCRIPTION The LND339 consists of four independent precision voltage comparators with an offset voltage as low as 2mV max for all four comparators, designed specifically to operate from a single power supply over a wide range of voltages. 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. 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. Application areas include limit comparators, simple analog to digital converters, pulse, squarewave and time delay generators: wide range VCO, MOS clock timers: multi vibrators and high voltage digital logic gates. The LND339 was designed to directly interface with TTL and CMOS. When the LND339 series is operated from both plus and minus power supplies, it will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators. FEATURES Wide supply voltage range (5 to 30VDC or ± 2.5 to ± 15VDC ) Very low supply current drain(0.8mA)independent of supply voltage Low input biasing current: (25nA) Low input offset current(±5nA) Offset voltage(±2mV) Input common-mode voltage range includes GND Differential input voltage range equal to the power supply voltage Output voltage compatible w...
