LM615 Quad Comparator and Adjustable Reference
December 1994
LM615 Quad Comparator and Adjustable Reference
General Description
The comparators have an input range which extends to the
negative supply and have open-collector outputs Improved
over the LM139 series the input stages of the comparators
have lateral PNP input transistors which enable low input
currents for large differential input voltages and swings
above V
a
The voltage reference is a three-terminal shunt-type band-
gap and is referred to the V
b
terminal Two resistors pro-
gram the reference from 1 24V to 6 3V with accuracy of
g
0 6% available The reference features operation over a
shunt current range of 17
mA
to 20 mA low dynamic imped-
ance broad capacitive load range and cathode terminal
voltage ranging from a diode-drop below V
b
to above V
a
As a member of National鈥檚 Super-Block
TM
family the
LM615 is a space-saving monolithic alternative to a multi-
chip solution offering a high level of integration without sac-
rificing performance
