Overview
The AS339AMTR-G1 is a quad precision voltage comparator manufactured by Diodes Incorporated. It features four independent comparators with a typical input offset voltage of 2.0mV and high gain. The device operates from a single power supply ranging from 2.0V to 36V or dual supplies from ±1.0V to ±18V. It has a low supply current drain of 0.9mA, which remains independent of the supply voltage magnitude. The component utilizes an open collector output configuration and is housed in a lead-free SO-14 package.
Feature Summary
- Four independent precision voltage comparators with low input offset voltage
- Wide operating voltage range supporting both single and split power supplies
- Low supply current drain that remains stable across varying supply voltages
- Open collector output configuration compatible with various logic families
Applications
- Battery Charger
- Cordless Telephone
- Switching Power Supply
- DC-DC Module
- PC Motherboard
Procurement Notes
Verify the specific ordering suffix to confirm compliance requirements. The 'G1' suffix indicates RoHS compliance and Green molding compound status, ensuring the product is halogen and antimony free. Confirm the package type matches design constraints, as this part number specifies the SO-14 variant. Ensure the procurement channel provides valid traceability for quality assurance purposes.
Selection Notes
Select the AS339AMTR-G1 when stringent input offset voltage specifications are required compared to standard AS339 variants. The SO-14 package is suitable for surface mount applications requiring compact board space. Consider the open collector output capability if interfacing with different voltage logic levels is necessary. Verify thermal management requirements based on the junction-to-ambient resistance characteristics of the chosen package.
Part Context
This component belongs to the AS339/339A series of low power, low offset voltage quad comparators. The AS339A designation denotes more stringent input offset voltage parameters than the standard AS339. The series is designed to be compatible with industry-standard 339 pinouts while offering improved performance metrics such as lower bias currents and higher gain.
Replacement Considerations
AS339MTR-G1 serves as a direct replacement for the standard AS339 variant within the same package and electrical family.
