Overview
The LMV7271MGX/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 consumes 9 µA of quiescent current per channel. The device features rail-to-rail inputs and a push-pull output stage capable of sourcing or sinking 34 mA. Key electrical parameters include a propagation delay of 1.8 µs, an input offset voltage of 4 mV, and a common-mode rejection ratio of 46 dB. It functions reliably across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Rail-to-rail input capability allows for maximum dynamic range in low-voltage applications.
- Push-pull output stage enables direct driving of digital logic without external pull-up resistors.
- Ultra-low power consumption supports battery-operated and space-constrained designs.
Applications
- Low voltage threshold detection circuits
- Level shifting between different voltage domains
- Simple on/off control systems
Procurement Notes
Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific tape-and-reel packaging configuration. Confirm that the SC-70-5 footprint matches your PCB layout requirements. Cross-reference the manufacturer's datasheet revision history to ensure compatibility with your design specifications regarding electrical characteristics and thermal performance.
Selection Notes
Select this component when a single comparator with rail-to-rail inputs and a push-pull output is required. It is suitable for applications needing low power consumption under 10 µA. Consider alternative models if open-drain outputs or higher speed propagation delays are necessary. Ensure the operating voltage stays within the 1.8 V to 5.5 V range for optimal performance.
Part Context
This device belongs to the LMV727x family of rail-to-rail input low power comparators. The family includes dual-channel variants like the LMV7272. These devices utilize a submicron silicon-gate BiCMOS process to achieve bipolar input noise performance with CMOS output swing capabilities. They are designed for space-critical designs requiring minimal PCB area.
Replacement Considerations
The LMV7271MFX/NOPB is a verified substitute offering identical functionality in an SOT-23-5 package. Verify pinout compatibility and thermal dissipation differences due to the change in package style before implementation.
