Overview
The JM38510/11202BGA is a military-grade dual precision voltage comparator manufactured by Texas Instruments. It operates from single or split power supplies ranging from 5.0VDC to 36VDC, or ±2.5VDC to ±18VDC. The device features very low supply current drain of 0.4 mA and low input biasing current of 25 nA typical. Maximum offset voltage is specified at +5mV max at 25°C. Input common-mode voltage range includes ground, and differential input voltage range equals the power supply voltage. Output saturation voltage is 250 mV at 4 mA typical. The output voltage is compatible with TTL, DTL, ECL, MOS, and CMOS logic systems.
Feature Summary
- High precision comparators with reduced offset voltage drift over temperature
- Eliminates need for dual supplies while allowing sensing near ground
- Compatible with all forms of logic including direct interface with MOS logic
Applications
- Limit comparators
- Simple analog to digital converters
- Pulse, squarewave and time delay generators
- Wide range VCOs
- MOS clock timers
Procurement Notes
Verify that the component meets Mil-Std-883, Method 5005 Group A conformance inspection requirements. Confirm the package type matches TO-99 (LMC) specifications. Ensure the part marking corresponds to JL193BGA or JM38510/11202BGA QACO as indicated in the packaging addendum. Validate operating temperature range covers -55°C to +125°C.
Selection Notes
Select this component for applications requiring high precision and low offset voltage in extreme environments. It is suitable for battery operation due to low power drain. Consider its compatibility with various logic families when designing interfaces. Ensure the design accounts for the open collector output configuration and potential oscillation issues without hysteresis.
Part Context
This part is a military version of the LM193 series. It shares functional characteristics with commercial variants like LM393 but offers extended temperature ranges and higher reliability standards. The BGA suffix indicates a specific TO-99 metal can package variant designed for rugged applications.
