LT1018CSW#TRPBF

Overview

The LT1018CSW#TRPBF is a micropower dual comparator in a 16-lead plastic SO package. It operates from a single 1.1V cell up to 40V with a typical supply current of 110µA. The device features a class B pull-up current source, eliminating external resistors. Key electrical parameters include a maximum offset voltage of 1mV and a maximum bias current of 15nA. Typical output drive capability is 70mA, and it supports driving loads connected to supplies more positive than the device.

Feature Summary

Features an internal class B pull-up current source that removes the need for external resistive pull-ups.
Output stage allows driving loads connected to a supply voltage higher than the device's V+.
On-chip trimming minimizes offset voltage while maintaining high gain and common mode rejection ratio.
Special circuitry prevents false output states even when inputs are overdriven.

Applications

Power supply monitors
Relay driving circuits
Oscillators

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging and lead-free compliance. Confirm the SW package designation corresponds to the 16-lead wide small outline form factor. Ensure the C grade temperature range matches the application requirements. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and current production status.

Selection Notes

Select this component when higher speed and drive current are required compared to the LT1017 variant. The 16-lead SW package offers additional pinout flexibility or isolation compared to 8-lead options. Verify that the 110µA supply current fits the power budget constraints. Ensure the operating voltage range covers the system's minimum and maximum supply levels.

Part Context

This part belongs to the LT1017/LT1018 family of general-purpose micropower comparators. While the LT1017 is optimized for lowest power consumption, the LT1018 provides higher speed and greater output drive capability. Both devices share pin compatibility with older dual comparator types like the 393 series, facilitating direct upgrades in existing designs.
