Visão Geral
Description
Key specifications:
- Resolution: 24 bits (no missing codes).
- Output data rate: 4.17 Hz to 470 Hz (adjustable).
- Interface: SPI-compatible.
- Power supply: 2.7V to 5.25V, with ultra-low power consumption (~400 µA).
Ideal for sensor interfaces (e.g., thermocouples, RTDs, strain gauges) in industrial, medical, and instrumentation systems. Its integrated features reduce external component count, simplifying design.
Package: TSSOP-24.
For detailed specs, refer to the datasheet.
