LT1017/LT1018

Micropower

Dual Comparator

FEATURES

DESCRIPTION

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.

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

30μA Supply Current (LT1017)

110μA Supply Current (LT1018)

Available in 8-Lead PDIP, 8-Lead Plastic S0, and

16-Lead Plastic SO Packages

Input speciﬁcations 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.
