Overview
The LMV393MMX is a dual general-purpose low-voltage analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5 V and features an open collector/open drain output type. The device exhibits a typical response time of 450 ns and consumes 140 uA of operating power. 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 a VSSOP-8 package and supports surface mount installation with an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual-channel architecture designed for low-voltage applications
- Open collector and open drain output configuration
- General-purpose performance with low current consumption
Applications
- Low-voltage signal processing circuits
- Battery-powered monitoring systems
- Space-constrained electronic designs
Procurement Notes
Verify the specific suffix 'MMX' against the manufacturer's official datasheet to confirm the tape-and-reel packaging format and quantity specifications. Ensure the component matches the required VSSOP-8 footprint and pinout for your PCB layout. Confirm RoHS compliance status through the latest official documentation before finalizing procurement orders.
Selection Notes
Select this component when a dual comparator is required for single-supply operation between 2.7 V and 5 V. Consider the 450 ns propagation delay and 7 mV offset voltage limits for precision requirements. The VSSOP-8 package is suitable for applications prioritizing board space efficiency over higher channel counts or wider voltage ranges found in other series.
Part Context
This part belongs to the LMV3xx series, which serves as the low-voltage counterpart to the industry-standard LM339/LM393 family. While maintaining similar functional characteristics, the LMV3xx series offers reduced current consumption and compatibility with lower supply voltages. The MMX designation indicates a specific reel-based packaging variant intended for automated surface-mount assembly processes.
Replacement Considerations
Direct substitutes include LMV393MM/NOPB for non-tape versions and LMV393DR for SOIC-8 packages. Verify pin compatibility and thermal characteristics when transitioning between VSSOP-8 and SOIC-8 footprints.
