General Description
The MAX31722/MAX31723 digital thermometers and thermostats with an SPI™/3-wire interface provide temperature readings that indicate the device temperature. No additional components are required; the devices
are truly temperature-to-digital converters. Temperature readings are communicated from the device over an SPI interface or a 3-wire serial interface.
