LT319AH

Overview

The LT319AH is a dual high-speed comparator housed in a 10-lead TO-5 metal can package. It operates within a supply voltage range of 5V to ±15V and features an operating temperature range of 0°C to 70°C. Key electrical specifications include a maximum input offset voltage of 8mV, a response time of 80ns, and a common mode rejection ratio of 90dB. The device provides open collector outputs capable of driving loads up to 25mA and includes integrated input protection diodes.

Feature Summary

• Features guaranteed maximum input offset voltage for precision applications
• Includes integrated input protection diodes for enhanced reliability
• Provides separate ground pin to isolate system grounds
• Capable of driving 25mA loads from each open collector output

Applications

• Window detectors
• High speed one shot circuits
• Relay and lamp drivers
• Voltage controlled oscillators

Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature rating. Ensure the selected variant matches the required thermal environment and physical footprint constraints for the target design.

Selection Notes

Select this component when high-speed switching with low offset error is required. Consider the TO-5 metal can package for environments requiring robust mechanical stability or specific mounting configurations compared to standard plastic packages.

Part Context

This part belongs to the LT119A/LM119/LT319A/LM319 family of dual comparators. It serves as an improved version offering lower input offset voltage and higher voltage gain compared to previous generations, making it suitable for demanding analog signal processing tasks.

Replacement Considerations

LT119AH#PBF is listed as an obsolete package option.
