LT1017/LT1018

Micropower
Dual Comparator
FEATURES

DESCRIPTION

The LT1017/LT1018 are general purpose micropower

comparators. The LT1017 is optimized for lowest operating 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 pullup 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.

Maximum Offset Voltage: 1mV

Maximum Bias Current: 15nA
Typical Output Drive: 70mA
Operates from 1.1V to 40V
Internal Pull-Up Current
Output Can Drive Loads Above V+
30A Supply Current (LT1017)
110A Supply Current (LT1018)
Available in 8-Lead PDIP, 8-Lead Plastic S0, and
16-Lead Plastic SO Packages

Input specications 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.
