Overview
The AS393MTR-E1 is a dual precision voltage comparator manufactured by Diodes Incorporated, housed in an SO-8 surface-mount package. It operates from a single supply ranging from 2V to 36V or split supplies of ±1.0V to ±18V. The device features a typical input offset voltage of 1.0mV and low supply current drain of 0.6mA. Electrical characteristics include a typical response time of 1.3µs and open-collector outputs. It functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual independent precision comparators with low input offset voltage
- Compatible with industry standard 393 pinout and functionality
- Open collector output configuration for flexible interfacing
- Low power supply current independent of voltage magnitude
Applications
- Battery chargers
- Switching power supplies
- DC-DC modules
- Communication equipment
Procurement Notes
Verify the specific ordering suffix E1 confirms RoHS compliance and lead-free status as defined by Diodes Incorporated. Confirm the package type matches the required SO-8 footprint. Ensure the design utilizes the correct tape and reel packing format associated with this part number variant. Cross-reference the marking ID on received components against official documentation.
Selection Notes
Select this component when a dual-channel comparator compatible with standard 393 specifications is required. Choose the AS393MTR-E1 over the AS393AMTR-E1 if the less stringent input offset voltage limits of the standard AS393 are acceptable. Verify that the single-supply operation range meets the system voltage requirements.
Part Context
This part belongs to the AS393/393A series of low-power, low-offset voltage dual comparators. It is designed to operate from wide voltage ranges using single or split power supplies. The series includes variants such as AS393P-E1 (PDIP) and AS393GTR-E1 (TSSOP), though some packages like TSSOP-8 are marked End of Life.
Replacement Considerations
The AS393MTR-G1 is listed as an alternative carrier for the same device. Other variants in the family include AS393AMTR-E1 and AS393MMTR-G1. Note that PDIP-8 and TSSOP-8 variants are End of Life without replacements.
