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

• [x] Support one-shot measurements
• [x] Support continuous measurements
• [x] Configurable sample rate / resolution
• [x] Configurable gain (PGA)
• [x] Configurable channel (only MCP3426/7/8)
• [x] Handle saturation values (high and low)
• [x] Docs
