General Description
The LP311isalow power versionofthe industry-standard
LM311.It takes advantageof stable high-value ion-implant- resistorsto performthe samefunctionasan LM311,with 30:1 reductionin power drain,but onlya6:1 slowdownof
response time. Thusthe LP311is well suitedfor battery-
powered applications,andall other applications wherefast
responseisnot needed.It operates overa wide rangeof
supply voltages from36V downtoa single3V supply, with
less than200mA drain,butitisstill capableof drivinga25
mAload.TheLP311is quite easytoapply withoutany oscil-
lation,if ordinary precautionsare takento minimize stray
coupling fromthe outputto either inputortothe balance
pins(as describedin the LM311 datasheet Application
Hints).
Features Low power drain,900mWon5V supply Operates from g15Vora single supplyaslowas3V Outputcan drive25mA Emitter outputcan swing below negative supply Response time:1.2ms Same pin-outas LM311 Low input currents:2nAof offset,15nAof bias Large common-mode input range: b14.6Vto 13.6V
with g15V supply
Applications Level-detectorfor battery-powered instruments Low-power lampor relay driver Low-power zero-crossing detector
