LP311 Datasheet | National Semiconductor

Description The LP311 is a low power version of the industry-standard LM311 It takes advantage of stable high-value ion-implanted resistors to perform the same function as an LM311 with a 30 1 reduction in power drain but only a 6 1 slowdown of response time Thus the LP311 is well suited for batterypowered applications and all other applications where fast response is not needed It operates over a wide range of supply voltages from 36V down to a single 3V supply with less than 200 m A drain but it is still capable of driving a 25 m A load The LP311 is quite easy to apply without any oscillation if ordinary precautions are taken to minimize stray coupling from the output to either input or to the balance pins (as described in the LM311 datasheet Application Hints) Features Y Y Y Y Y Y Y Y Low power drain 900 m W on 5V supply Operates from g 15V or a single supply as low as 3V Output can drive 25 m A Emitter output can swing below negative supply Response time 1 2 ms Same pin-out as LM311 Low input currents 2 n A of offset 15 n A of bias Large mon-mode input range b14 6V to 13 6V with g 15V supply Applications Level-detector for battery-powered instruments Low-power lamp or relay driver Low-power zero-crossing detector Schematic Diagram TL H 5711 - 7 Connection Diagram Dual-In-Line Package Order Number LP311M or LP311N See NS Package Numbers M08A or N08E TL H 5711 - 4 Top View C1995 National Semiconductor Corporation TL H 5711 RRD-B30M115 Printed in U S A Absolute Maximum Ratings If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Total Supply Voltage (V8 - 4) Collector Output to Negative Supply Voltage (V7 - 4) Collector Output to Emitter Output Emitter Output to Negative Supply Voltage (V1 - 4) Differential Input Voltage Input Voltage (Note 1) 36V 40V 40V g 30V g 30V g 15V Power Dissipation (Note 2) Output Short Circuit Duration Operating Temperature...
