TYPICAL APPLICATION
DESCRIPTION
Micropower
Dual Comparator
The LT
®
1017/LT1018 are general purpose micropower
comparators. The LT1017 is optimized for lowest operat-
ing power while the LT1018 operates at higher power and
higher speed. Both devices can operate from a single 1.1V
cell up to 40V. The output stage includes a class “B” pull-
up current source, eliminating the need for an external
resistive pull-up and saving power. The output stage is
also designed to allow driving loads connected to a supply
more positive than the device, as can comparators with
open-collector output stages.
Input specifi cations are also excellent. On-chip trimming
minimizes offset voltage, while high gain and common
mode rejection ratio keep other input referred errors low.
Common mode voltage range includes ground. Special
circuitry prevents false output states even if the input is
overdriven.
The LT1017/LT1018 are pin compatible with older dual
comparators such as 393 type devices.
