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

The voltage reference is a three-terminal shunt-type band-

gram the reference from 124V to 63V with accuracy of

g

06% 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

the

LM615 is a space-saving monolithic alternative to a multi-

chip solution offering a high level of integration without sac-

rificing performance
