Overview
The LMV393MX 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. The device features an open collector/drain output type and a response time of 450 ns. Key electrical parameters 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 and supports surface mount installation. The component functions reliably across a temperature range from -40°C to +85°C.
Feature Summary
- Dual-channel architecture for general-purpose signal comparison
- Low voltage operation capability down to 2.7 V
- Open collector or open drain output configuration
Applications
- Low voltage signal processing circuits
- Battery-powered monitoring systems
- General purpose threshold detection
Procurement Notes
Verify the specific suffix MX against official Texas Instruments documentation to confirm the SOIC-8 package and commercial temperature grade (-40°C to +85°C). Ensure compatibility with 2.7 V to 5 V supply requirements. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when low voltage operation between 2.7 V and 5 V is required. Consider the 450 ns response time and 140 uA current consumption for power-sensitive designs. Verify that the SOIC-8 package fits the board layout constraints. Confirm that the commercial temperature range meets the application environment needs.
Part Context
The LMV393MX belongs to the LMV393 series of low-voltage comparators from Texas Instruments. This series serves as a low-power alternative to standard comparators, designed for space-constrained applications. The device integrates two independent comparators in a compact package, offering a balance of performance and power efficiency for portable electronics.
Replacement Considerations
LMV393IDR: Offers similar functionality but with an extended industrial temperature range up to +125°C and a faster 200 ns response time.
