Overview
The LM293MDREP is a dual differential comparator from Texas Instruments, designed for operation from a single power supply over a wide voltage range. It features an 8-pin SOIC surface-mount package with a response time of 300 ns. The device supports a maximum supply voltage of 36 V and operates within a temperature range of -55°C to +125°C. Key electrical specifications include a quiescent current of 500 uA, a maximum output current per channel of 6 mA, an input offset voltage of 5 mV, and an input bias current of 250 nA.
Feature Summary
- Dual independent voltage comparators optimized for single-supply operation across a wide voltage spectrum
- High-speed performance with a typical response time of 300 ns
- Robust industrial-grade reliability with an extended operating temperature range from -55°C to +125°C
Applications
- General-purpose analog signal comparison circuits
- Voltage monitoring systems requiring wide supply tolerance
- Industrial control logic interfaces
Procurement Notes
Verify the specific suffix 'REP' against the manufacturer's official documentation to confirm it denotes an enhanced product variant or specific packaging configuration. Ensure the 8-SOIC package dimensions match the target PCB footprint. Confirm that the -55°C to +125°C temperature rating aligns with the environmental requirements of the final assembly.
Selection Notes
Select this component when dual comparators are required in a compact surface-mount format. The 36 V maximum supply voltage allows for direct interfacing with higher voltage rails without additional level shifting. The low quiescent current makes it suitable for battery-powered applications where standby power consumption is critical.
Part Context
This part belongs to the LM293 series of analog comparators manufactured by Texas Instruments. The series is characterized by its ability to operate from a single power supply, making it a versatile choice for various electronic designs. The LM293MDREP specifically utilizes the SOIC-8 package, distinguishing it from through-hole variants like the LM293P.
Replacement Considerations
The LM293DR is listed as a comparable alternative within the same family. Verify pinout compatibility and ensure the replacement meets the required temperature and electrical specifications.
