概要
Description
Key specifications:
- Input range: 0V to VREF (2.5V max).
- On-chip track-and-hold and 2.5V internal reference.
- Single-supply operation (2.7V to 5.5V).
Applications include battery monitoring, industrial control, and sensor interfaces. The TSSOP-16 package ensures compact PCB integration.
For detailed specs, refer to the datasheet.
