DATA SHEET
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 with
TTL,DTL ECL MOS and CMOS logic
systems.
ADVANTAGES
• High precision comparators
• Reduced VOS drift over temperature
• Power drain suitable for battery operation
• Allows sensing near ground
• Compatible with all forms of logic
• Eliminates need for dual supplies
