Overview
The LMV7271MF is a single-channel analog comparator from Texas Instruments, characterized by rail-to-rail input and push-pull output capabilities. It operates within a supply voltage range of 1.8 V to 5.5 V, consuming as little as 9 µA of supply current per channel. The device features a propagation delay of 800 ns and an input offset voltage of 4 mV. It supports a maximum output current of 34 mA per channel and offers a common-mode rejection ratio of 46 dB. The component is housed in an SC-70-5 package and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Rail-to-rail input stage utilizing bipolar transistors for improved noise performance.
- Push-pull output stage enabling operation with minimum power consumption when driving loads.
- Low power consumption design suitable for space-critical applications.
- Advanced submicron silicon-gate BiCMOS process construction.
Applications
- Level-shifting applications
- Low voltage circuit designs
- Space-constrained PCB layouts
Procurement Notes
Verify the specific suffix 'MF' against official Texas Instruments documentation to confirm the exact package type and tape/reel specifications. Ensure compatibility with the required operating temperature range and supply voltage constraints before integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status.
Selection Notes
Select this component for designs requiring low power consumption and rail-to-rail input compatibility. The push-pull output is advantageous for driving loads directly without additional pull-up resistors. Consider the SC-70-5 package size for applications where board space is limited. Verify that the 800 ns propagation delay meets the timing requirements of the target application.
Part Context
The LMV7271MF belongs to the LMV727x family of rail-to-rail input low power comparators. This series includes single (LMV7271), dual (LMV7272), and open-drain output (LMV7275) variants. The devices are built using Texas Instruments’ advanced submicron silicon-gate BiCMOS process, offering a balance of speed, power efficiency, and compact packaging options like SC-70 and SOT-23.
