Overview
The LM293DGKR is a dual differential voltage comparator manufactured by Texas Instruments, designed for single-supply operation. It features an SOIC-8 surface-mount package and operates within a supply voltage range of 2 V to 30 V. The device draws a typical operating current of 500 uA per channel and provides an output current capability of 6 mA. Key electrical specifications include a maximum input offset voltage of 5 mV, an input bias current of 250 nA, and a propagation delay of 300 ns. It supports CMOS and TTL logic levels and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Dual differential inputs with open-collector outputs compatible with various logic families
- Wide single-supply voltage operation from 2 V to 30 V
- Rail-to-rail common-mode input voltage range including ground
- High output drive capability suitable for direct interfacing
Applications
- Overvoltage and undervoltage detection circuits
- Window comparator designs
- Temperature sensing threshold monitoring
- Level shifting between different voltage domains
Procurement Notes
Verify the specific suffix 'DGKR' against the manufacturer's official datasheet to confirm the SOIC-8 package type and tape-and-reel packaging configuration. Ensure that the component meets the required RoHS compliance standards for your assembly process. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a dual comparator with wide supply voltage tolerance is required. It is suitable for applications needing rail-to-rail input capability without negative supply rails. Consider the 300 ns propagation delay for timing-sensitive designs. Verify that the open-drain output architecture aligns with the pull-up requirements of the downstream circuitry.
Part Context
This device belongs to the LMx93/LM2903 family of dual differential comparators from Texas Instruments. These components are engineered for robust performance in general-purpose analog switching applications. The series is characterized by its ability to operate from a single power supply while maintaining compatibility with standard digital logic interfaces.
Replacement Considerations
LM293DR serves as a pin-compatible alternative within the same product family.
