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
b
. The common
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
a
.
The 1.2V voltage reference, referred to the V
b
terminal, is a
two-terminal shunt-type band-gap similar to the LM185-1.2
series, with voltage accuracy of
g
0.6% available. The refer-
ence features operation over a shunt current range of 17
m
A
to 20 mA, low dynamic impedance, and broad capacitive
load range.
As a member of National’s Super-Block
TM
family, the
LM612 is a space-saving monolithic alternative to a multi-
chip solution, offering a high level of integration without sac-
rificing performance.
