Overview
The LMV393IPWG4 is a dual low-voltage analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and consumes 210 uA of operating current. The device features a response time of 200 ns, an input offset voltage (Vos) of 7 mV, and an input bias current (Ib) of 250 nA. It utilizes a TSSOP-8 package for surface mount installation and supports differential input types with open collector or open drain outputs.
Feature Summary
- Dual-channel architecture designed for general-purpose comparison tasks
- Low-voltage operation capability suitable for battery-powered applications
- Rail-to-rail input functionality for extended common-mode voltage range
Applications
- Battery-powered monitoring systems
- Threshold detection circuits
- General-purpose signal comparison
Procurement Notes
Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the manufacturer's latest documentation. Confirm the TSSOP-8 package dimensions match the target PCB footprint requirements. Ensure the open-drain output configuration aligns with the pull-up resistor requirements of the downstream logic interface.
Selection Notes
Select this component when low supply voltage operation between 2.7 V and 5.5 V is required. Consider the 200 ns propagation delay for timing-sensitive applications. Evaluate the 210 uA quiescent current against power budget constraints. Verify that the TSSOP-8 package size fits the available board space compared to alternative packages like SOIC.
Part Context
This part belongs to the LMV393 series of low-voltage comparators from Texas Instruments. It shares functional similarities with other members of the family but differs in packaging and specific electrical characteristics such as input bias current and offset voltage compared to higher-speed or higher-voltage variants.
Replacement Considerations
LMV393IDRG4 offers identical electrical specifications but utilizes an SOIC-8 package instead of TSSOP-8. LMV393IPWR provides the same performance metrics in a different tape-and-reel packaging format.
