Overview
The LMV7239M7X is a single-channel analog comparator manufactured by Texas Instruments, housed in a SC-70-5 surface-mount package. It operates within a supply voltage range of 2.7 V to 5.5 V and features rail-to-rail input capability with a common-mode voltage extending down to -100 mV. The device provides a push-pull output capable of sourcing 60 mA per channel. Key electrical parameters include a propagation delay of 75 ns, an input offset voltage of 6 mV, and a quiescent current of 95 µA. It supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Rail-to-rail input stage allows signal sensing near ground and supply rails.
- Push-pull output architecture eliminates the need for external pull-up resistors.
- Ultra-low power consumption suitable for battery-operated systems.
Applications
- General-purpose threshold detection circuits
- Voltage monitoring applications
- Signal conditioning in low-voltage embedded systems
Procurement Notes
Verify the specific suffix 'M7X' against the manufacturer's official documentation to confirm pinout compatibility and active status. Ensure the SC-70-5 package dimensions match the target PCB footprint. Confirm that the commercial grade temperature rating (-40°C to +85°C) meets the operational requirements of the final assembly environment.
Selection Notes
Select this component when a single comparator with rail-to-rail inputs and a push-pull output is required in a minimal footprint. It is appropriate for designs needing low static current and fast response times under single-supply conditions. Compare against the automotive-grade LMV7239Q1 if extended temperature ranges or AEC-Q100 qualification are necessary for the application.
Part Context
This part belongs to the LMV7239 series of ultra-low power comparators. It shares functional similarities with the LMV7219 but offers different performance characteristics regarding speed and output drive. The SC-70-5 package is designed for space-constrained portable electronics and industrial control modules requiring efficient power management.
Replacement Considerations
LMV7239M7/NOPB: Pin-compatible alternative with identical electrical specifications in the same SC-70-5 package.
FAQ
Does the LMV7239M7X require an external pull-up resistor?
No, it features a push-pull output stage that can drive loads directly without external pull-up components.
What is the minimum supply voltage for operation?
The device operates correctly with a supply voltage as low as 2.7 V.
