Overview
The LMV393M 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 power current. The device features an open collector/open drain output type and exhibits a response time of 450 ns. Key electrical parameters include an 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 with SMD/SMT installation style and supports a temperature range from -40 C to +85 C.
Feature Summary
- Dual channel configuration for general-purpose comparison tasks
- Low voltage operation capability down to 2.7 V
- Open collector or open drain output structure
Applications
- Low voltage signal processing circuits
- Space-constrained electronic designs requiring tiny packages
- Temperature monitoring systems within specified ranges
Procurement Notes
Verify the specific ordering suffix and manufacturer part number against official Texas Instruments documentation to ensure compatibility with design requirements. Confirm RoHS compliance status and packaging details such as tube quantities directly with authorized distributors or the manufacturer before procurement. Cross-reference datasheet revisions to validate electrical characteristics and mechanical dimensions.
Selection Notes
Select this component when low voltage operation between 2.7 V and 5 V is required alongside minimal space constraints due to the SOIC-8 package. Consider the 450 ns response time and 140 uA current consumption for applications where moderate speed and low power are prioritized over high-speed performance. Ensure the operating environment stays within the -40 C to +85 C commercial temperature range.
Part Context
The LMV393M belongs to the LMV3xx series, which includes single, dual, and quad low-voltage comparators. These devices serve as low-voltage versions of industry-standard parts like the LM339 and LM393, offering reduced current consumption while maintaining compatibility with standard logic families. The series is designed for applications requiring operation from 2.7 V to 5 V with wide temperature stability.
Replacement Considerations
LMV393MMX/NOPB: Dual channel, VSSOP-8 package, 450 ns response time, 2.7 V to 5 V supply, 140 uA current. LMV393IDR: Dual channel, SOIC-8 package, 200 ns response time, 2.7 V to 5.5 V supply, 100 uA current.
