Overview
The LMV393MMX/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/open drain output type with 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 8-VSSOP package and supports surface mount installation across a temperature range of -40°C to +85°C.
Feature Summary
- Dual-channel architecture for compact signal comparison
- Low voltage operation optimized for single-supply systems
- Open collector/drain output configuration for flexible interfacing
Applications
- General purpose analog-to-digital signal conversion
- Voltage monitoring circuits
- Threshold detection applications
Procurement Notes
Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS status as documented in official datasheets. Confirm the 'MMX' suffix corresponds to the VSSOP-8 package and reel/cut-tape packaging options. Ensure the component meets the required -40°C to +85°C industrial temperature grade for the intended environment.
Selection Notes
Select this component when low power consumption is critical alongside dual-channel functionality. The 2.7 V minimum supply voltage makes it suitable for battery-operated devices. Compare against higher-speed comparers if the 450 ns response time is insufficient for the application speed requirements.
Part Context
This part belongs to the LMV393 series, which represents the low-voltage version of the industry-standard LM393. While the standard LM393 operates up to 36 V, the LMV393 is specifically designed for low-voltage applications ranging from 2.7 V to 5.5 V, offering reduced power consumption at the cost of lower maximum supply voltage tolerance.
Replacement Considerations
LMV393IDGKR: Alternative pin-compatible option in 8-TSSOP/MSOP package.
