Overview
The LM339BIRTER is a quad analog comparator manufactured by Texas Instruments, housed in a WQFN-16 surface-mount package. It operates within a supply voltage range of 2 V to 36 V and supports CMOS and TTL output logic levels. The device features a differential input type with an input offset voltage of 370 uV and an input bias current of 25 nA. It delivers a response time of 1 us and provides an output current per channel of 21 mA while consuming 1 mA of operating supply current. The component functions across a temperature range from -40 C to +85 C.
Feature Summary
- Integrates four independent differential comparators into a single compact integrated circuit for signal processing applications.
- Provides flexible digital interface compatibility through CMOS and TTL output types without requiring external pull-up components for specific logic families.
- Operates reliably across a wide industrial temperature range suitable for demanding environmental conditions.
Applications
- Over-voltage and under-voltage detection circuits
- Temperature sensing and control systems
- Voltage monitoring and level shifting
Procurement Notes
Verify the specific suffix IRTER corresponds to the WQFN-16 package and Reel/Cut Tape packaging options as listed in official distributor specifications. Confirm RoHS compliance status directly with the manufacturer datasheet before integration. Ensure the ordering part number matches the exact pinout and thermal pad requirements for the target PCB layout design.
Selection Notes
Select this component when a quad comparator configuration is required with low input bias current characteristics. The WQFN-16 package offers a space-efficient solution for dense board layouts compared to traditional leaded packages. Consider the 370 uV input offset voltage specification if high precision is necessary for the application threshold settings.
Part Context
This device belongs to the LM339B series of analog comparators from Texas Instruments. It shares functional similarities with other members of the family but differs in specific electrical parameters such as offset voltage and package style. The LM339B variant typically offers improved performance metrics over standard LM339 versions.
