Converting continuously varying analog voltages or currents into digital signals recognizable by an MCU serves as a bridge between the analog world and digital processors.

1. High-precision resolution: Categorized by bit depth (e.g., 12, 16, or 24 bits); higher bit counts yield finer resolution, enabling the detection of minute signals.

2. Multi-channel acquisition: Multi-channel ADCs can simultaneously acquire data on voltage, temperature, current, and sensor signals.

3. Industrial/Measurement-grade ADCs: Featuring low temperature drift and low noise, these are suitable for applications such as power monitoring, weighing systems, temperature sensing, and instrumentation.

4. Digital bus output: Supports interfaces like I2C and SPI for direct data transmission to the MCU for processing.
