Overview
The LT1018IS8#PBF is a micropower dual comparator from Analog Devices, optimized for higher speed compared to the LT1017 variant. It operates on a single supply voltage ranging from 1.1V to 40V. The device features an internal Class B pull-up current source that eliminates the need for external resistive pull-ups. It provides a typical output drive of 70mA and includes special circuitry to prevent false output states during input overdrive. The part is housed in an 8-lead Plastic SO package and supports an industrial temperature range.
Feature Summary
- Internal Class B pull-up current source eliminates external resistive pull-up requirements
- Output stage capable of driving loads connected to a supply more positive than V+
- On-chip trimming minimizes offset voltage while maintaining high gain and common mode rejection
- Special circuitry prevents false output states even if inputs are overdriven
Applications
- Power supply monitors
- Relay driving circuits
- Oscillators
Procurement Notes
Verify the specific suffix IS8 corresponds to the Industrial temperature grade (-40°C to 85°C) and the 8-lead Plastic Small Outline package. Confirm the #PBF designation indicates lead-free compliance. Ensure the ordering information matches the manufacturer's current datasheet specifications for this exact part number before finalizing procurement.
Selection Notes
Select the LT1018IS8#PBF when higher switching speed is required compared to the LT1017 series. This component is suitable for applications requiring operation from low voltages down to 1.1V up to 40V. Consider its pin compatibility with older dual comparators like the 393 type devices for direct replacements in existing designs.
Part Context
This component belongs to the LT1017/LT1018 family of general-purpose micropower comparators manufactured by Analog Devices (formerly Linear Technology). While the LT1017 is optimized for lowest operating power, the LT1018 variant operates at higher power levels to achieve higher speed performance. Both share similar electrical characteristics and packaging options.
Replacement Considerations
The LT1018IS8#PBF is pin compatible with older dual comparators such as 393 type devices.
