Overview
The LT1017CN8#PBF is a micropower dual comparator manufactured by Analog Devices Inc. It operates from a single supply voltage ranging from 1.1V to 40V. The device features an internal class B pull-up current source, eliminating the need for external resistive pull-ups. Key electrical specifications include a maximum offset voltage of 1mV and a maximum bias current of 15nA. Typical output drive capability reaches 70mA. The unit is housed in an 8-lead PDIP package and supports an operating temperature range of 0°C to 70°C.
Feature Summary
- Integrated Class B pull-up current source eliminates external resistors
- On-chip trimming minimizes input offset voltage
- Special circuitry prevents false outputs during overdrive conditions
- Pin compatible with legacy dual comparator designs
Applications
- Power supply monitors
- Relay driving circuits
- Oscillator implementations
Procurement Notes
Verify the specific suffix CN8 corresponds to the commercial temperature grade (0°C to 70°C) and PDIP-8 package configuration. Confirm that the #PBF designation indicates lead-free compliance as per manufacturer standards. Ensure the component matches the original Linear Technology or Analog Devices manufacturing origin to guarantee parameter consistency.
Selection Notes
Select this component when low quiescent power consumption is critical alongside general-purpose comparison functions. The internal pull-up simplifies board layout compared to open-collector alternatives. Verify that the required response speed aligns with the device's typical propagation delay characteristics for the intended application frequency.
Part Context
This part belongs to the LT1017/LT1018 family of micropower comparators. The LT1017 variant is specifically optimized for minimum operating power, distinguishing it from the higher-speed LT1018. Both share identical pinouts and core architecture, allowing for flexible design choices based on power versus speed requirements within the same package footprint.
