Overview
The LM293ADGKR is a dual differential voltage comparator manufactured by Texas Instruments. It operates on a single power supply ranging from 2 V to 30 V. The device features an open-collector output compatible with CMOS and TTL logic families. Key electrical specifications include a maximum response time of 1.3 µs, a quiescent supply current of 1 mA, and a maximum input offset voltage of 2 mV. Each channel provides an output current capability of 6 mA. The component is housed in an SOIC-8 surface-mount package.
Feature Summary
- Dual differential input configuration for precise voltage comparison
- Open-collector outputs ensure compatibility with various logic families
- Operates effectively across a wide single-supply voltage range
Applications
- Overvoltage and undervoltage detection circuits
- Window comparator designs
- Level shifting applications
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 format. Ensure the A-grade temperature rating aligns with system requirements. Cross-reference the ordering number with authorized distributors to validate authenticity and traceability before finalizing procurement.
Selection Notes
Select this component when a dual-channel comparator with low supply current and wide voltage tolerance is required. The open-collector output simplifies interfacing with different logic levels. Consider the SOIC-8 package for space-constrained PCB layouts. Verify that the 1.3 µs propagation delay meets the timing constraints of the target application compared to faster alternatives.
Part Context
This part belongs to the LMx93/LM2903 series of dual comparators designed for single-supply operation. These devices are engineered for general-purpose voltage monitoring tasks where cost-effectiveness and broad supply voltage compatibility are prioritized over high-speed performance. The series supports standard industrial applications requiring reliable differential input handling.
Replacement Considerations
LM293ADR serves as a direct pin-compatible alternative within the same product family.
