Overview
The LT319AN#PBF is a dual comparator housed in a 14-lead plastic DIP package. It operates from a single 5V supply or dual ±15V supplies, featuring a maximum input offset voltage of 0.5mV and an 80ns response time. The device provides 25mA drive capability from open collector outputs and includes integrated input protection diodes.
Feature Summary
- Dual comparator architecture with separate ground pin for system isolation
- Integrated input protection diodes limiting differential input voltage
- 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 suffix AN#PBF to confirm the 14-lead plastic DIP package and commercial temperature range (0°C to 70°C). Ensure compatibility with existing board layouts requiring this specific footprint and lead configuration.
Selection Notes
Select this component when low input offset voltage and high common mode rejection are required. It serves as an improved alternative to legacy LM119 devices, offering better performance metrics while maintaining similar functionality for general-purpose comparison tasks.
Part Context
This part belongs to the LT119A/LT319A family of dual comparators manufactured by Analog Devices Inc. It is designed to replace older LM119/LM319 units with enhanced specifications including lower offset voltage and guaranteed common mode rejection ratios.

FAQ
What is the maximum differential input voltage allowed?
The inputs are protected with back-to-back zener diodes, limiting the maximum differential input voltage to ±5V if current is unlimited.
Can the device operate with a single supply?
Yes, the LT319A can operate from a single 5V supply or dual supplies ranging up to ±15V.
