Overview
The LMV331M7-NS is a single-channel general-purpose analog comparator manufactured by National Semiconductor. It operates on a single supply voltage ranging from 2.7 V to 5 V and consumes a typical operating current of 120 uA. The device features an open collector/open drain output type and is housed in a SC-70-5 surface-mount package. Key electrical parameters include a maximum input offset voltage of 7 mV, an input bias current of 250 nA, and an input offset current of 50 nA. It supports a wide operating temperature range from -40°C to +85°C.
Feature Summary
- Single-channel general-purpose low-voltage comparator design
- Open collector or open drain output configuration
- Low power consumption suitable for battery-operated systems
- Compact SC-70-5 tiny pack packaging
Applications
- Analog signal to digital output conversion
- Threshold detection circuits
- Voltage monitoring applications
Procurement Notes
Verify the specific suffix 'NS' against official National Semiconductor documentation to confirm it denotes a standard commercial grade variant without unique functional deviations. Confirm RoHS compliance status as datasheets may vary by revision. Ensure the SC-70-5 footprint matches your PCB layout requirements. Check for obsolescence notices as older National Semiconductor parts may have been transitioned to Texas Instruments production lines.
Selection Notes
Select this component when a single comparator with low voltage operation is required. The open-drain output necessitates an external pull-up resistor; ensure the selected resistor value aligns with your system's speed and voltage level requirements. Verify that the 7 mV max input offset voltage meets your precision needs. Consider the SC-70-5 package size constraints during mechanical design.
Part Context
This part belongs to the LMV331 family of general-purpose, low-voltage comparators originally developed by National Semiconductor. The family includes single (LMV331), dual (LMV393), and quad (LMV339) variants. These devices are designed for applications requiring low power and small form factors. National Semiconductor was acquired by Texas Instruments, which now manages the product line.
Replacement Considerations
The LMV331M7X/NOPB is a verified alternate part number listed in distributor databases for this component. Other compatible replacements within the same family include the LMV393 (dual) and LMV339 (quad). Verify pin compatibility and electrical specifications before substituting.
