JL193BGA

Overview

The JL193BGA is a military-grade dual precision voltage comparator manufactured by Texas Instruments, conforming to the LM193JAN specification. It operates within a wide supply voltage range of 5.0VDC to 36VDC or ±2.5VDC to ±18VDC. The device features a maximum input offset voltage of 5.0 mV at 25°C and a typical supply current drain of 0.4 mA. Input bias current is typically 25 nA, with an input common-mode voltage range that includes ground. The output saturation voltage is typically 250 mV at 4 mA, ensuring compatibility with TTL, DTL, ECL, MOS, and CMOS logic systems.

Feature Summary

• High precision comparators with low offset voltage specifications designed for accurate signal comparison.
• Wide supply voltage operation allows flexibility in single or split power supply configurations.
• Low power supply current drain independent of supply voltage magnitude, suitable for battery operation.
• Output voltage compatible with various logic families including TTL, CMOS, and MOS systems.

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 against the Package Option Addendum to confirm the exact variant, such as JM38510/11202BGA, which indicates Mil-Std-883 compliance. Ensure the TO-99 metal can package matches the design requirements. Confirm RoHS status and lead finish details directly from the manufacturer's latest documentation before procurement, as these attributes vary by sub-group and revision.

Selection Notes

Select this component when high precision and low offset voltage are critical for the application. The wide input common-mode range including ground makes it suitable for single-supply designs where sensing near ground is required. Consider the low power consumption if battery life is a constraint. Verify that the open-loop gain and response time meet the speed requirements of the specific circuit topology.

Part Context

The JL193BGA belongs to the LM193 series of dual precision voltage comparators. It is a military-grade version (JAN) of the standard LM193, offering enhanced reliability and performance under extreme conditions. The device is housed in a TO-99 metal can package, providing robust protection and thermal stability. It is designed to interface directly with various logic families without additional level shifting components.

Replacement Considerations

Direct substitutes include other LM193 variants such as LM193JAN or LM193CDR, provided they meet the specific MIL-STD-883 requirements. Verify pinout compatibility and electrical characteristics, particularly offset voltage and supply current, to ensure seamless integration into existing designs without modification.
