Overview
The LT1716CS5#TRMPBF is a micropower precision comparator in a 5-lead TSOT-23 package. It operates on supply voltages from 2.7V to 44V with 35µA quiescent current. The Over-The-Top input stage allows common mode voltages up to 44V above V–, independent of V+. It features rail-to-rail output swing and an internal pull-up current source. The device includes built-in input protection for faults up to 5V below the negative supply.
Feature Summary
- Over-The-Top input capability extending 44V above the negative supply
- Micropower operation with 35µA typical quiescent current
- Rail-to-rail output swing with internal pull-up current source
- Built-in input protection against negative supply faults
Applications
- Power supply monitors
- Relay and lamp drivers
- Oscillators
- Peak detectors
- Level shifting circuits
Procurement Notes
Verify the #TRMPBF suffix indicates tape and reel packaging containing 500 units. Confirm the CS5 designation corresponds to the commercial temperature range of –40°C to 85°C. Ensure the component matches the 5-lead TSOT-23 physical package dimensions specified in the datasheet.
Selection Notes
Select this part for applications requiring high common mode voltage tolerance relative to the negative rail while maintaining low power consumption. The internal pull-up eliminates external resistors, simplifying design. Verify that the 35µA quiescent current meets system power budgets and that the 44V input range covers the maximum expected signal levels.
Part Context
This component belongs to the LT1716 family of micropower precision comparators manufactured by Analog Devices. It shares functional characteristics with other parts in the series but is distinguished by its specific package type and temperature grade. The family is designed for low-voltage single-supply operations and high-voltage monitoring tasks.

FAQ
Can the inputs withstand voltages significantly higher than the positive supply?
Yes, the inputs can be taken up to 44V above V–, independent of the V+ supply voltage.
Does the output require an external pull-up resistor?
No, the output stage includes a class B pull-up current source, eliminating the need for an external resistive pull-up.
What is the maximum differential input voltage?
The maximum differential input voltage is 44V.
