Overview
The LM293DRG3 is a dual differential analog comparator manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates on a single supply voltage ranging from 2 V to 30 V with a typical quiescent current of 500 uA. The device features open-collector outputs compatible with CMOS and TTL logic levels, delivering up to 6 mA per channel. Key electrical specifications include a maximum input offset voltage of 5 mV, an input bias current of 250 nA, and a response time of 300 ns.
Feature Summary
- Dual differential voltage comparison capability designed for single-supply operation
- Open-collector output structure enabling direct interface with various digital logic families
- Input common-mode voltage range extends to ground level
Applications
- General-purpose voltage monitoring circuits
- Threshold detection systems
- Logic interface adapters between analog sensors and digital controllers
Procurement Notes
Verify the specific suffix 'G3' against the manufacturer's official documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the selected package variant matches the required PCB footprint and thermal management constraints for the target application environment.
Selection Notes
Select this component when low power consumption is critical alongside standard switching speeds. The wide supply voltage range accommodates diverse system architectures without requiring additional level shifting. Verify that the open-collector output requirements align with the pull-up resistor network design of the downstream circuitry.
Part Context
This part belongs to the LMx93 family of dual comparators, which are industry-standard devices for basic voltage thresholding. The LM293 variant typically offers wider operating temperature ranges compared to commercial grade parts, making it suitable for broader industrial applications while maintaining cost-effectiveness.
Replacement Considerations
LM293DR: Identical functional equivalent without the G3 suffix designation.
