LM193AJRLQMLV

Overview

The LM193AJRLQMLV is a dual precision voltage comparator manufactured by Texas Instruments under the LM193QML series. It features an input offset voltage specification as low as 2.0 mV maximum and operates from a single power supply ranging from 2.0 VDC to 36 VDC, or split supplies of ±1.0 V to ±18 V. The device provides very low supply current drain of 0.4 mA independent of supply voltage. It includes radiation guarantees for Total Ionizing Dose up to 100 krad(Si) and is ELDRS free at 100 krad(Si). The input common-mode voltage range includes ground, and the output is compatible with TTL, DTL, ECL, MOS, and CMOS logic systems.

• Wide range voltage controlled oscillators (VCO)

Procurement Notes

Verify that the component matches the specific LM193QML radiation qualification requirements. Confirm the package type corresponds to the CDIP variant associated with this part number. Ensure compliance with MIL-STD-883 testing standards if required for the application environment.

Selection Notes

Select this component when high precision comparison is required in radiation-hardened environments. The low offset voltage ensures accurate threshold detection. The wide supply voltage range allows flexibility in power system design without requiring dual supplies.

Part Context

This device belongs to the LM193A/LM193QML family of low power, low offset voltage dual comparators. It is designed specifically for operation from a single power supply over a wide range of voltages while maintaining high precision characteristics suitable for demanding applications.
