Overview
The LM193 MDR is a dual precision voltage comparator manufactured by Texas Instruments, supplied in a die package format. It operates from a single power supply ranging from 2.0 VDC to 36 VDC or split supplies of ±1.0 VDC to ±18 VDC. The device features a very low supply current drain of 0.4 mA, independent of the supply voltage. Input common-mode voltage includes ground, and differential input voltage equals the supply voltage. Output saturation voltage is 250 mV at 4 mA sink current. It interfaces directly with TTL, DTL, ECL, MOS, and CMOS logic systems.
Feature Summary
- Designed for operation from a single power supply over a wide voltage range
- Input common-mode voltage range includes ground even on single supply
- Low power supply current drain independent of supply voltage magnitude
- Output voltage compatible with TTL, DTL, ECL, MOS, and CMOS logic systems
Applications
- Limit comparators
- Simple analog to digital converters
- Pulse and squarewave time delay generators
- Wide range voltage-controlled oscillators (VCO)
- MOS clock timers
Procurement Notes
Verify that the procurement channel provides authentic Texas Instruments components. Confirm the specific die package configuration matches system integration requirements. Ensure handling procedures account for the exposed die nature of the component to prevent electrostatic discharge damage during storage and installation.
Selection Notes
Select this component when high precision comparison is required with minimal power consumption. It is suitable for applications needing direct interfacing with various logic families without additional level shifting. Consider the die package constraints for PCB layout and thermal management compared to standard packaged alternatives.
Part Context
The LM193 series consists of two independent low voltage comparators designed specifically for single-supply operation. It offers low input bias and offset currents, making it ideal for battery-operated systems. The series eliminates the need for dual supplies while allowing sensing near ground potential.
Replacement Considerations
Public confirmed substitute part numbers include LM193AH/883, LM193AJ/883, LM193H/883, and LM193J/883.
