MAX31826 Description
The MAX31826 digital thermometer provides 12-bit temperature measurements and municates over a 1-Wire® bus that by definition requires only one data line (and ground) for munication with a central microcontroller. It has a -55°C to +125°C operating temperature range and is accurate to ±0.5°C over the -10°C to +85°C range. In addition, the device can derive power directly from the data line (“parasite power”),...
