LM612
Dual-Channel Comparator and Reference
General Description
The dual-channel comparator consists of two individual
comparators having an input voltage range that extends
down to the negative supply voltage V
open-collector output can be driven low by either half of the
LM612 This configuration makes the LM612 ideal for use
as a window comparator The input stages of the compara-
tor have lateral PNP input transistors which maintain low
input currents for large differential input voltages and swings
above V
The 1 2V voltage reference referred to the V
two-terminal shunt-type band-gap similar to the LM185-1 2
series with voltage accuracy of
ence features operation over a shunt current range of 17 mA
to 20 mA low dynamic impedance and broad capacitive
load range
As a member of National’s Super-Block
LM612 is a space-saving monolithic alternative to a multi-
chip solution offering a high level of integration without sac-
rificing performance
