General Description
The LP311 is a low power version of the industry-standard
LM311 It takes advantage of stable high-value ion-implant-
ed 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 battery-
powered 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 A drain but it is still capable of driving a 25
mA load The LP311 is quite easy to apply without any oscil-
lation 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
