LMV7275MG/NOPB

Overview

The LMV7275MG/NOPB is a single-channel analog comparator from Texas Instruments, housed in an SC-70-5 surface-mount package. It operates within a supply voltage range of 1.8 V to 5.5 V and draws a typical quiescent current of 14 µA per channel. The device features rail-to-rail input capability and an open-drain output stage capable of sourcing up to 34 mA. Key electrical specifications include a maximum input offset voltage of 4 mV, an input bias current of 10 nA, and an input offset current of 200 pA. Common-mode rejection ratio is specified at 46 dB, while power supply rejection ratio reaches 55 dB. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Rail-to-rail input stage enables accurate signal detection near supply rails
• Open-drain output supports wired-OR configurations and level-shifting applications
• Ultra-low power consumption suitable for battery-operated systems

Applications

• Low-voltage portable electronics requiring minimal power draw
• Space-constrained circuit designs utilizing compact SC-70 packaging
• Level-shifting interfaces between different logic voltage domains

Procurement Notes

Verify the specific suffix MG/NOPB against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the SC-70-5 footprint matches your PCB layout constraints. Confirm that the open-drain output architecture aligns with your system's pull-up requirements and logic levels before finalizing procurement.

Selection Notes

Select this component when designing low-power circuits requiring rail-to-rail input sensitivity. The open-drain output necessitates an external pull-up resistor, which must be chosen based on desired switching speed and load voltage. Consider the 4 mV maximum input offset voltage for precision threshold applications. Verify that the 14 µA quiescent current meets strict energy budget requirements compared to higher-speed alternatives.

Part Context

This part belongs to the LMV727x family of rail-to-rail input low-power comparators manufactured using submicron silicon-gate BiCMOS process technology. The family includes variants with push-pull outputs, such as the LMV7271, offering different output drive characteristics. The LMV7275 specifically provides an open-drain configuration, distinguishing it from its push-pull counterparts within the same series.

Replacement Considerations

The LMV7271MGX/NOPB serves as a functional substitute if a push-pull output is preferred over open-drain. Both devices share identical input characteristics and power consumption profiles. Verify that the target application can accommodate the change from open-drain to push-pull output topology without affecting circuit performance.
