Overview
The LT1017CSW#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 is 70mA. The unit is housed in a 16-lead Plastic SO package (SW) with an operating temperature range of 0°C to 70°C.
Feature Summary
- Optimized for lowest operating power consumption within the LT1017/LT1018 family
- Internal Class B pull-up current source eliminates external resistive pull-up requirements
- Output stage allows driving loads connected to a supply more positive than the device
- 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 the specific suffix #PBF indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the SW package designation corresponds to the 16-lead wide plastic small outline format. Ensure the 'C' grade matches the required commercial temperature range of 0°C to 70°C for the target application environment.
Selection Notes
Select this component when low quiescent current is critical compared to the higher speed LT1018 variant. The internal pull-up simplifies board layout and reduces component count. Verify that the 70mA typical sink current meets load requirements. Consider the 16-pin footprint if pin compatibility with legacy 393-type devices is necessary but space allows for the wider SOIC package.
Part Context
This part belongs to the LT1017/LT1018 series of general-purpose micropower comparators. The LT1017 variant is specifically optimized for minimum power usage, whereas the LT1018 offers higher speed at increased power consumption. Both share similar input characteristics and are designed to operate from a single cell up to 40V.
Replacement Considerations
LT1017CH is a pin-compatible alternative in an 8-lead PDIP package.
