The Device

The Microchip MCP3425 is a low-current 16-bit analog-to-digital converter.

The device has an I²C interface and an on-board ±2048mV reference.

Variants MCP3426/7/8 are very similar, but support multiple input channels. They are supported as well, but require to enable one of the following Cargo features:

• dual_channel for MCP3426/7

• quad_channel for MCP3428

Status

• Support one-shot measurements

• Support continuous measurements

• Configurable sample rate / resolution

• Configurable gain (PGA)

• Configurable channel (only MCP3426/7/8)

• Handle saturation values (high and low)
