Overview
The LM293DRG4 is a dual differential analog comparator manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates on a single power supply ranging from 2 V to 30 V or dual supplies up to ±15 V. The device features two independent channels with a typical response time of 300 ns and a quiescent supply current of 500 uA. Each channel provides an output current capability of 6 mA. Input characteristics include a maximum input offset voltage of 5 mV and an input bias current of 250 nA. The component functions within a temperature range of -25°C to +85°C.
Feature Summary
- Dual-channel differential comparison architecture for independent signal processing
- Open-collector output configuration compatible with CMOS and TTL logic families
- Low-power operation with minimal supply current consumption across wide voltage ranges
Applications
- Over-voltage and under-voltage detection circuits
- Battery monitoring and management systems
- Sensor threshold detection interfaces
Procurement Notes
Verify the specific suffix DRG4 against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest product information sheet. Ensure the procurement source provides valid traceability data for this discontinued lifecycle stage component.
Selection Notes
Select this component when a low-cost, dual-channel comparator is required for general-purpose signal switching applications. It is suitable for designs needing open-collector outputs to interface with various logic levels. Consider the 300 ns response time for timing-critical signals and verify that the 2 V minimum supply voltage aligns with the system power architecture.
Part Context
This part belongs to the LM293 series of dual differential comparators from Texas Instruments. It shares functional similarities with the LM393 but offers specific performance characteristics tailored for industrial and commercial environments. The device is designed for robust operation in standard voltage domains commonly found in consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with legacy equivalents such as the LM293D or LM393 based on pinout and electrical parameter matching.
