LT1017/LT1018
Micropower
Dual Comparator
FEATURES DESCRIPTION n The LT®1017/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. n 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 …
