LP311 Datasheet Lp311 Voltage Comparator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LP311 Voltage Comparator February 1995 LP311 Voltage Comparator General.

General 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 mA drain but it is still capable of driving a 25 mA 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)

Key Features

  • Y Y Y Y Y Y Y Y Low power drain 900 mW on 5V supply Operates from g 15V or a single supply as low as 3V Output can drive 25 mA Emitter output can swing below negative supply Response time 1 2 ms Same pin-out as LM311 Low input currents 2 nA of offset 15 nA of bias Large common-mode input range b14 6V to 13 6V with g 15V supply.
