Overview
The LMV393MX/NOPB is a dual general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5 V and consumes 140 uA of operating current. The device features an open collector/drain output type and exhibits a response time of 450 ns. Input characteristics include a maximum input offset voltage (Vos) of 7 mV, an input bias current (Ib) of 250 nA, and an input offset current (Ios) of 50 nA. It is housed in an SOIC-8 package for surface mount installation and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual-channel low-voltage operation with supply range from 2.7 V to 5 V
- Open collector/drain output configuration for flexible interfacing
- Low power consumption suitable for battery-operated applications
- Wide common-mode input voltage range including ground
Applications
- General-purpose signal comparison circuits
- Low-voltage monitoring systems
- Threshold detection applications
Procurement Notes
Verify the specific suffix MX/NOPB against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the SOIC-8 package dimensions match the target PCB footprint. Confirm that the 450 ns propagation delay meets system timing requirements. Check for any recent product change notices affecting electrical parameters or manufacturing location.
Selection Notes
Select this component when a dual comparator is required for low-voltage single-supply designs. The LMV393MX/NOPB offers lower current consumption compared to standard bipolar comparators like the LM393. Consider the 7 mV input offset voltage for precision requirements. The open-drain output necessitates an external pull-up resistor for proper logic level translation.
Part Context
This part belongs to the LMV3xx series, which are low-voltage versions of the industry-standard LM339/LM393 family. The series is designed for space-constrained applications using tiny packages. It provides improved performance over predecessors while maintaining pin-out compatibility with legacy designs in many configurations.
Replacement Considerations
LMV393ID: Same functional specifications but may differ in packaging or qualification status.
