Overview
The LT319AN is a dual high-speed comparator manufactured by Analog Devices Inc. It features an open collector output capable of driving loads up to 25mA. The device operates from a single 5V supply or dual supplies up to ±15V. Key electrical specifications include a maximum input offset voltage of 8mV, a typical response time of 80ns, and a maximum input bias current of 1200nA. It utilizes a 14-lead plastic DIP package and supports an operating temperature range from 0°C to 70°C.
Feature Summary
- Features guaranteed maximum input offset voltage for precision applications
- Includes integrated input protection diodes
- Provides separate ground pin for system ground isolation
- Capable of driving 25mA loads directly from open collector outputs
Applications
- Window detectors
- High speed one shot circuits
- Relay and lamp drivers
- Voltage controlled oscillators
Procurement Notes
Verify the specific part marking matches the datasheet identification. Confirm the package type corresponds to the 14-lead plastic DIP configuration. Ensure the temperature grade aligns with the required operational environment. Check for lead-free finish compliance if mandated by project specifications. Validate that the ordering suffix indicates the correct manufacturing lot.
Selection Notes
Select this component when high-speed comparison is required alongside significant load drive capability. The separate ground pin facilitates isolation between different system grounds. Consider the input offset voltage limits for precision threshold detection. Evaluate the power supply requirements against the available single or dual rail options. Assess the thermal performance within the specified operating temperature range.
Part Context
This device belongs to the LT119A/LT319A family of dual comparators. It serves as an improved version of previous LM119/LM319 designs. The series offers lower input offset voltage and higher voltage gain. It maintains compatibility with standard logic families while providing robust output stages.
Replacement Considerations
LT319AN#PBF is the verified lead-free equivalent part number.
