Overview
The AS393GTR-E1 is a dual precision voltage comparator from the AS393 series, manufactured by Diodes Incorporated. It operates on a single supply voltage 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. It utilizes an open collector output configuration with a maximum sink current of 16mA. The component is housed in a TSSOP-8 package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual independent precision comparators designed for wide single or split power supply operation
- Low input bias current and low input offset voltage for high accuracy applications
- Open collector output structure allowing flexible interfacing with various logic families
Applications
- Battery chargers
- Cordless telephones
- Switching power supplies
- DC-DC modules
- PC motherboards
Procurement Notes
Verify the specific ordering suffix 'E1' against the manufacturer's latest documentation to confirm compliance status and availability. Confirm that the TSSOP-8 package variant aligns with the intended PCB footprint and thermal requirements. Check for any End-of-Life notices or recommended replacement part numbers prior to finalizing procurement plans.
Selection Notes
Select this component when a dual comparator with low offset voltage and wide supply range is required. Ensure the design accommodates the open collector output nature, which necessitates external pull-up resistors. Verify that the TSSOP-8 package dimensions fit within the available board space constraints.
Part Context
This part belongs to the AS393/393A family of low-power, low-offset voltage dual comparators. It is compatible with industry standard 393 pinouts but offers improved performance characteristics such as lower offset voltage. The GTR suffix indicates the TSSOP-8 surface-mount package type.
Replacement Considerations
The datasheet explicitly states that all variants in the TSSOP-8 package are End of Life without replacements. No alternative part numbers are provided by the manufacturer for this specific package configuration.
