LT1017/LT1018 Micropower Dual Comparator FEATURES DESCRIPTION n Maximum Offset Voltage: 1mV The LT 1017/LT1018 are general purpose micropower n Maximum Bias Current: 15nA comparators. The LT1017 is optimized for lowest operat- n Typical Output Drive: 70mA ing power while the LT1018 operates at higher power and n Operates from 1.1V to 40V higher speed. Both devices can operate from a single 1.1V n Internal Pull-Up Current cell up to 40V. The output stage includes a class B pull- + n Output Can Drive Loads Above V up current source, eliminating the need for an external n resistive pull-up and saving power. The output stage is 30A Supply Current (LT1017) also designed to allow driving loads connected to a supply 110A Supply Current (LT1018) n more positive than the device, as can comparators with Available in 8-Lead PDIP, 8-Lead Plastic S0, and open-collector output stages. 16-Lead Plastic SO Packages Input speci cations are also excellent. On-chip trimming minimizes offset voltage, while high gain and common APPLICATIONS mode rejection ratio keep other input referred errors low. n Power Supply Monitors Common mode voltage range includes ground. Special n Relay Driving circuitry prevents false output states even if the input is n Oscillators overdriven. L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
