Overview
The AS393GTR-G1 is a dual precision voltage comparator manufactured by Diodes Incorporated, housed in an 8-pin TSSOP package. It operates from a single supply of 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. Key electrical parameters include a response time of 1.3µs, output sink current of 16mA, and an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual independent precision comparators with wide supply voltage compatibility
- Low power consumption with supply current independent of voltage magnitude
- Open collector outputs capable of driving various logic families
Applications
- Battery chargers
- Switching power supplies
- DC-DC modules
- Communication equipment
Procurement Notes
Verify the specific ordering suffix 'GTR' corresponds to the TSSOP-8 package and tape & reel packing format. Confirm RoHS compliance and green molding compound status as indicated by the G1 suffix. Ensure design-in approval accounts for the End-of-Life (EOL) status associated with this package variant.
Selection Notes
Select this component when a compact surface-mount solution is required for dual comparison tasks. The TSSOP-8 package offers space efficiency compared to standard SO-8. Consider the EOL status of the TSSOP-8 variant when planning long-term production runs and evaluate alternative packages like SO-8 or MSOP-8 for new designs.
Part Context
This part belongs to the AS393/393A series of low-power, low-offset voltage dual comparators. It is compatible with industry-standard 393 pinouts. While the AS393A variant offers stricter offset voltage specifications, the standard AS393 provides general-purpose performance suitable for most analog switching applications.
Replacement Considerations
The datasheet explicitly states that all variants in the TSSOP-8 package are End of Life without replacements. Designers should transition to the AS393MTR-G1 (SO-8) or AS393MMTR-G1 (MSOP-8) for new implementations.
