Overview
The LM193JG is a dual differential comparator manufactured by Texas Instruments, designed for operation from single or dual power supplies. It operates within a supply voltage range of 2 V to 36 V and supports an operating temperature range of -55°C to +125°C. The device features low supply current drain of 0.4 mA per comparator, low input bias current of 25 nA, and low input offset voltage of 2 mV. It includes open-drain outputs compatible with TTL, MOS, and CMOS logic families.
Feature Summary
- Dual independent voltage comparators designed for wide single-supply or dual supply operation
- Low supply current drain that remains independent of the supply voltage
- Open-drain output configuration allowing wired-AND relationships and flexible logic level shifting
- Common-mode input voltage range extends down to ground potential
Applications
- Chemical or gas sensor interfaces
- Desktop PC system monitoring
- AC induction motor control circuits
- Precision weigh scale applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official package addendum to confirm the exact physical package type and material specifications. Ensure the component meets all required environmental standards and reliability ratings for the intended application environment before finalizing procurement decisions.
Selection Notes
Select this component when a ruggedized dual comparator with extended temperature capability is required. The open-drain output facilitates interfacing with various logic families. Consider the input common-mode voltage limits relative to the supply voltage when designing the signal conditioning circuitry for optimal performance.
Part Context
This part belongs to the LM193-MIL family of dual differential comparators. It shares functional similarities with the LM293, LM393, and LM2903 series but offers military-grade temperature ranges and robust packaging options suitable for demanding industrial environments.
