Overview
The AS339GTR-G1 is a low power, low offset voltage quad comparator manufactured by Diodes Incorporated. It integrates four independent precision comparators within a single TSSOP-14 package. The device operates from a single supply ranging from 2.0V to 36V or dual supplies of ±1.0V to ±18V. Key electrical characteristics include a typical input offset voltage of 2.0mV, a supply current drain of 0.9mA, and an open collector output configuration.
Feature Summary
- Four independent precision voltage comparators integrated in a compact surface-mount package
- Operates effectively across wide single and split power supply voltage ranges
- Features low input bias current and low input offset voltage for high accuracy
- Open collector outputs allow flexible interfacing with various logic families
Applications
- Battery Charger
- Cordless Telephone
- Switching Power Supply
- DC-DC Module
- PC Motherboard
Procurement Notes
Verify the specific ordering suffix 'G1' confirms the TSSOP-14 package format and RoHS/Green compliant status. Confirm that the 'TR' designation indicates Tape & Reel packaging rather than tube packing. Ensure the component matches the exact manufacturer part number to avoid confusion with standard SOIC variants or non-green alternatives.
Selection Notes
Select this component when a quad comparator solution is required with low power consumption and precise offset voltage specifications. The TSSOP-14 package offers a smaller footprint compared to standard SOIC options. Consider the open collector output type for compatibility with different logic levels and ensure the operating temperature range meets system requirements.
Part Context
This component belongs to the AS339/339A series of low power comparators designed for general-purpose applications. The 'G1' suffix specifically denotes the TSSOP-14 package variant which is lead-free and halogen-free. This series provides industry-standard pinouts compatible with other popular quad comparator designs while offering improved thermal performance in the thin profile package.

FAQ
What is the maximum differential input voltage rating?
The absolute maximum differential input voltage rating is 40V.
Does the supply current drain vary with supply voltage magnitude?
No, the low power supply current drain is independent of the magnitude of the power supply voltage.
