Overview
The LM193AHRQMLV is a dual precision voltage comparator manufactured by Texas Instruments, designed for high-reliability applications. It operates from a single or split power supply ranging from 2.0 VDC to 36 VDC (±18 VDC). The device features low input offset voltage of up to 4.0 mV maximum and very low supply current drain of 0.4 mA typical. It includes radiation guarantees with Total Ionizing Dose tolerance of 100 krad(Si) and is ELDRS free. The input common-mode voltage range includes ground, allowing sensing near ground potential even on single supplies.
Feature Summary
- Radiation guaranteed performance with 100 krad(Si) TID tolerance
- ELDRS free design suitable for space environments
- Low power operation with supply current independent of voltage magnitude
- Input common-mode voltage range includes ground
Applications
- Limit comparators
- Simple analog to digital converters
- Pulse and squarewave time delay generators
- Wide range VCOs
- MOS clock timers
Procurement Notes
Verify the specific ordering suffix matches the required package type and qualification level. Confirm that the component meets MIL-STD-883 Method 5005 Group A requirements if specified for military use. Ensure radiation testing data aligns with project environmental constraints. Check for RoHS compliance status as indicated in the packaging information. Validate the part marking against the datasheet specifications.
Selection Notes
Select this component when radiation hardness is critical for the application environment. Consider the wide supply voltage range for flexibility in power system design. Evaluate the low input bias current for high-impedance sensor interfaces. Verify that the open-collector output configuration fits the logic interface requirements. Assess thermal dissipation capabilities based on the TO-99 package characteristics.
Part Context
This device belongs to the LM193 series of low power, low offset voltage dual comparators. It is specifically qualified under the QML standard for military and defense applications. The series is designed to operate directly from single power supplies over a wide voltage range while maintaining compatibility with TTL, DTL, ECL, MOS, and CMOS logic systems.
Replacement Considerations
Public confirmed substitute part numbers include LM193AJRQMLV and LM193AHRLQMLV.
