Overview
The AS339MTR-E1 is a quad precision voltage comparator manufactured by Diodes Incorporated, housed in an SOIC-14 surface-mount package. It operates on a single supply from 2.0V to 36V or dual supplies of ±1.0V to ±18V. The device features a typical input offset voltage of 2.0mV and low supply current drain of 0.9mA. Electrical characteristics include a response time of 1.3µs, output sink current of 16mA, and open collector outputs. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Four independent precision comparators with wide supply voltage compatibility
- Low power consumption with supply current independent of voltage magnitude
- Open collector outputs allowing flexible interfacing with various logic families
- Input common mode voltage range includes ground potential
Applications
- Battery charger circuits
- Cordless telephone systems
- Switching power supply control
- DC-DC module regulation
- PC motherboard monitoring
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm compliance status and packaging type. Confirm that the component meets required environmental directives such as RoHS standards before integration into final assemblies. Ensure proper handling procedures are followed due to moisture sensitivity classification.
Selection Notes
Select this component for designs requiring multiple independent voltage comparisons within a compact footprint. Consider the open collector output configuration when designing pull-up resistor networks. Evaluate thermal resistance values if operating near maximum junction temperatures in enclosed environments.
Part Context
This part belongs to the AS339 series of low-power, low-offset voltage quad comparators. It serves as a general-purpose analog comparator suitable for replacing industry standard equivalents. The device provides high gain and precise threshold detection capabilities for signal conditioning applications.
Replacement Considerations
AS339MTR-G1 is listed as an alternative variant within the same product family.
