개요
Description
- 10-bit resolution (0–1023 values).
- 8 single-ended or 4 pseudo-differential inputs.
- SPI interface (simple serial communication).
- 3.3V–5V operation (compatible with most systems).
- Low power consumption (suitable for embedded projects).
Commonly used for reading sensors (e.g., potentiometers, temperature sensors), it bridges analog signals to digital systems efficiently. The I/SL suffix denotes its SOIC package.
Example use: Measuring multiple analog sensors with a microcontroller.
For setup, connect to a controller’s SPI pins and use libraries (e.g., `spidev` for Raspberry Pi).
Pros: Easy to use, affordable.
Cons: Limited resolution vs. higher-end ADCs.
Ideal for basic analog sensing in DIY electronics.
