Overview
The AS339MTR-G1 is a low power, low offset voltage quad comparator manufactured by Diodes Incorporated. It features four independent precision comparators with a typical input offset voltage of 2.0mV and high gain. Designed for single supply operation from 2.0V to 36V or split supplies of ±1.0V to ±18V, it maintains low power supply current drain independent of voltage magnitude. The device utilizes an open collector output configuration and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Low input bias current of 25nA (typical) and low input offset voltage of 2.0mV (typical)
- Wide supply voltage range supporting single supply (2.0V to 36V) and dual supply operation
- Open collector outputs allow flexible interfacing with various logic families
- Input common mode voltage range includes ground potential
Applications
- Battery Charger
- Cordless Telephone
- Switching Power Supply
- DC-DC Module
- PC Motherboard
Procurement Notes
Verify the specific ordering suffix to confirm package type and compliance status. The MTR suffix indicates Tape & Reel packaging in SOIC-14 format. Confirm RoHS and Green molding compound requirements against project specifications. Ensure compatibility with existing PCB footprints for SOIC-14 packages before finalizing procurement decisions.
Selection Notes
Select this component when low power consumption and wide supply voltage flexibility are required. The open collector output necessitates external pull-up resistors for proper logic level translation. Consider the AS339AMTR-G1 variant if stricter input offset voltage specifications are necessary for the application design.
Part Context
This part belongs to the AS339/339A series of low power quad comparators. It is compatible with industry standard 339 devices. The AS339 variant offers standard input offset voltage specifications compared to the more stringent AS339A version. The device is designed for general-purpose analog comparison tasks in consumer and industrial electronics.
Replacement Considerations
AS339AMTR-G1 serves as a direct replacement with tighter input offset voltage specifications. AS339GTR-G1 provides the same functionality in a TSSOP-14 package instead of SOIC-14. Verify pinout compatibility and thermal characteristics when substituting between package types.
FAQ
What is the maximum differential input voltage?
The absolute maximum rating for differential input voltage is 40V.
Can the input common mode voltage go negative?
No, the input common-mode voltage should not be allowed to go negatively by more than 0.3V at +25°C.
Is the supply current dependent on the supply voltage?
No, the low power supply current drain is independent of the magnitude of the power supply voltage.
