Overview
The LMV7275MG 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 consumes 14 µA of quiescent current. The device features rail-to-rail input capability and an open-drain output capable of sourcing 34 mA. Key electrical specifications include a maximum input offset voltage of 4 mV, input bias current of 10 nA, and input offset current of 200 pA. Common-mode rejection ratio is 46 dB, while power supply rejection ratio is 55 dB. It functions reliably across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Rail-to-rail input stage allows signal detection near ground and positive supply rails
- Open-drain output configuration supports flexible interfacing with various logic families
- Low quiescent current consumption enables efficient operation in battery-powered systems
Applications
- Battery-operated portable devices requiring low power monitoring
- Threshold detection circuits in consumer electronics
- General-purpose voltage level sensing applications
Procurement Notes
Verify the specific suffix 'MG' against the manufacturer's official datasheet to confirm pinout and package dimensions. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering part number with the latest Texas Instruments documentation to avoid discrepancies between legacy and updated revisions.
Selection Notes
Select this component when a single comparator with rail-to-rail inputs is required in a compact SC-70-5 package. It is suitable for designs needing low power consumption under 14 µA and operation down to 1.8 V. Consider the open-drain output if external pull-up resistors are acceptable for logic level translation.
Part Context
This part belongs to the LMV7275 series of low-voltage comparators. It is designed for general-purpose applications where space and power efficiency are critical constraints. The device integrates a single comparator channel optimized for performance in small form-factor packages commonly used in modern mobile and handheld electronic devices.
Replacement Considerations
Consult the Texas Instruments product selection guide for direct equivalents within the LMV727x family. Verify pin compatibility and electrical parameters before substituting with other single-channel comparers from different manufacturers.
