LT1017IS8#TRPBF

Overview

The LT1017IS8#TRPBF is a micropower dual comparator in an 8-lead plastic SO package. It operates from a single 1.1V to 40V supply with a typical supply current of 30µA. The device features a class B pull-up current source, eliminating the need for external resistive pull-ups. Key electrical specifications include a maximum offset voltage of 1mV, a maximum bias current of 15nA, and a typical output drive capability of 70mA. The operating temperature range extends from -40°C to +85°C.

Feature Summary

Optimized for lowest operating power consumption among general-purpose comparators
Integrated Class B pull-up current source removes requirement for external resistive components
Output stage allows driving loads connected to a supply more positive than the device V+
On-chip trimming minimizes offset voltage while maintaining high gain and common mode rejection

Applications

Power supply monitors
Relay driving circuits
Oscillators

Procurement Notes

Verify that the ordering suffix #TRPBF confirms the tape and reel packaging format and lead-free status as specified by Analog Devices. Confirm the 'I' grade designation matches the required -40°C to +85°C industrial temperature range for your specific application environment before finalizing procurement.

Selection Notes

Select this component when low quiescent current is critical compared to the higher speed LT1018 variant. Ensure the design accommodates the internal pull-up current source characteristics rather than relying on traditional open-collector outputs. Verify that the 8-pin SOIC footprint aligns with the PCB layout constraints and that the 70mA sink current meets load requirements.

Part Context

This part belongs to the LT1017/LT1018 family of micropower dual comparators manufactured by Analog Devices (formerly Linear Technology). The LT1017 variant specifically targets ultra-low power applications, contrasting with the LT1018 which offers higher speed at increased power consumption. The series maintains pin compatibility with older dual comparator designs like the 393 type devices.
