Overview
The LM393ADGKR is a dual differential comparator manufactured by Texas Instruments, belonging to the LM393A series. It features a VSSOP-8 surface-mount package and supports single or dual power supplies ranging from 4 V to 30 V. The device operates with a typical supply current of 2.5 mA and offers a response time of 1.3 µs. Key electrical specifications include an input offset voltage of 2 mV, an input bias current of 250 nA, and an input offset current of 50 nA. It functions within a temperature range of 0°C to +70°C and provides CMOS and TTL compatible outputs.
Feature Summary
- Dual differential comparison architecture for precise signal threshold detection
- CMOS and TTL output compatibility for broad digital interface integration
- Low power consumption design suitable for battery-operated applications
Applications
- Over-voltage and under-voltage protection circuits
- Window comparator designs for monitoring signal levels
- Temperature sensing interfaces using thermistor bridges
Procurement Notes
Verify the specific suffix 'DGKR' corresponds to the VSSOP-8 tape-and-reel packaging configuration. Confirm that the 'A' grade designation meets the required input offset voltage specifications for the target application. Ensure compliance with RoHS directives as indicated in manufacturer documentation before final procurement approval.
Selection Notes
Select this component when dual comparators are required in a compact VSSOP-8 footprint. It is appropriate for systems operating between 4 V and 30 V where low quiescent current is beneficial. Consider the 1.3 µs propagation delay for timing-sensitive applications and ensure the 2 mV offset voltage aligns with the necessary measurement accuracy requirements.
Part Context
This part belongs to the LM393 family of low-power dual voltage comparators. The LM393ADGKR specifically denotes the A-grade version with enhanced offset voltage characteristics compared to standard grades. It shares functional similarities with other variants like the LM393AD but differs in packaging and performance grading.
Replacement Considerations
LM393ADGKRG4 is a verified equivalent variant within the same product line.
