Overview
The LM193AJRQMLV is a low power, low offset voltage dual comparator manufactured by Texas Instruments. It operates from a single supply ranging from 2.0 VDC to 36 VDC or split supplies of ±1.0 VDC to ±18 VDC. The device features an input common-mode voltage range that includes ground and a differential input voltage range equal to the supply voltage. It provides open-collector outputs compatible with TTL, DTL, ECL, MOS, and CMOS logic systems. The component is qualified under QMLV standards for radiation resistance up to 100 krad(Si) and is ELDRS free.
Feature Summary
- Radiation guaranteed performance with Total Ionizing Dose tolerance of 100 krad(Si)
- ELDRS free design suitable for space applications
- Low input bias current and low input offset voltage specifications
- Output voltage compatible with various logic families including TTL and CMOS
Applications
- Limit comparators
- Simple analog to digital converters
- Pulse, squarewave and time delay generators
- Wide range VCOs
- MOS clock timers
Procurement Notes
Verify the specific ordering suffix 'QMLV' confirms the required radiation qualification level and ELDRS-free status. Ensure the package type matches the mechanical drawing requirements for your assembly process. Confirm compliance with MIL-STD-883 Method 5005 Group A inspection levels if mandated by your system specifications.
Selection Notes
Select this component when high precision comparison is required in environments with ionizing radiation. The wide single-supply voltage range allows for direct interfacing with various logic families without additional level shifting. Consider the low power drain characteristics for battery-operated systems where minimizing energy consumption is critical.
Part Context
This part belongs to the LM193 series of dual precision voltage comparators. It is designed specifically for operation from a single power supply over a wide range of voltages. The series offers unique characteristics such as an input common-mode voltage range that includes ground, even when operated from a single power supply voltage.
