ADC 2 Click carries MCP3551, which is a 22-bit ADC with automatic internal offset and gain calibration. This high precision analog-to-digital converter has total unadjusted error of less than 10 ppm, and low-output noise of 2.5 µV RMS. The board carries two pairs of screw screw terminals: VIN- for bringing in reference voltage, VIN+ for the positive voltage. VCC out and GND are output voltages. The Click communicates with the target board through mikroBUS CS, CSK and MISO lines. Can use either a 3.3V or 5V power supply.
