Overview
The AS339AMTR-E1 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 from ±1.0V to ±18V, it maintains low supply current drain independent of voltage magnitude. The device offers open collector outputs, includes ground in the common mode range, and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Low input offset voltage of 2.0mV (typical) for precision applications
- Wide single supply voltage range from 2.0V to 36V
- Open collector output configuration compatible 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 RoHS compliance status as the E1 suffix indicates lead-free construction. Confirm package type is SO-14. Check ordering information for production status, as this specific variant may be marked NRND. Ensure design-in alternatives are identified if end-of-life actions apply. Validate datasheet revision DS36838 Rev. 3-2 for accurate electrical limits.
Selection Notes
Select the AS339A variant over the standard AS339 when stricter input offset voltage specifications are required. The AS339A guarantees a maximum offset of 5mV compared to 7mV for the AS339. Choose this component for general-purpose comparisons requiring low power consumption and wide supply voltage tolerance. Verify thermal resistance requirements for the SO-14 package during layout.
Part Context
This part belongs to the AS339/339A series of low power quad comparators. It is compatible with industry standard 339 devices. The AS339A sub-series provides more stringent input offset voltage performance than the base AS339 model. The series supports both single and dual supply operations with low supply current drain that remains stable across the operating voltage range.
Replacement Considerations
AS339AMTR-G1 is listed as an alternative in the ordering information table.
