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
The voltage reference is a three-terminal shunt-type band-
gap and is referred to the V
gram the reference from 1 24V to 6 3V with accuracy of
g
shunt current range of 17 A to 20 mA low dynamic imped-
ance broad capacitive load range and cathode terminal
voltage ranging from a diode-drop below V
As a member of National’s Super-Block
LM615 is a space-saving monolithic alternative to a multi-
chip solution offering a high level of integration without sac-
rificing performance
