Overview
The LMV393IDGKRG4 is a dual general-purpose low-voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open collector/open drain output type. The device exhibits a typical response time of 200 ns and a maximum input offset voltage (Vos) of 7 mV. Input bias current (Ib) is specified at 250 nA, with a common-mode voltage range extending down to -100 mV. It supports a maximum output current of 23 mA per channel and functions reliably across an operating temperature range from -40°C to +125°C.
Feature Summary
- Dual-channel architecture designed for general-purpose analog comparison tasks
- Low-voltage operation capability supporting single-supply systems
- Open collector/drain output configuration for flexible interfacing
Applications
- Battery-powered equipment requiring low quiescent current
- Threshold detection circuits in consumer electronics
- On-off control applications in industrial monitoring
Procurement Notes
Verify the specific package marking and date code against the manufacturer's latest datasheet revision to ensure component authenticity. Confirm that the ordering suffix matches the required tape-and-reel packaging specifications. Cross-reference the RoHS compliance status with current environmental regulations applicable to your region before finalizing procurement orders.
Selection Notes
Select this component when a dual comparator is needed for low-voltage applications under 5.5 V. Ensure the design accommodates the open-drain output requirement, which necessitates external pull-up resistors. Verify that the 200 ns propagation delay meets the system timing constraints and that the -40°C to +125°C temperature range covers the operational environment.
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 is distinguished by its SOIC-8 or VSSOP-8 package options and specific electrical characteristics optimized for portable and battery-operated devices. The 'RG4' suffix indicates lead-free construction and RoHS compliance.
Replacement Considerations
LMV393IDGKR is a direct pin-compatible alternative within the same series.
