Maxim MAX31629 I2C Digital Thermometer & Real-Time Clock (RTC)

Maxim MAX31629 I²C Digital Thermometer
& Real-Time Clock (RTC)

Maxim's MAX31629 I2C Digital Thermometer & Real-Time Clock (RTC) integrates the critical functions of a real-time clock and a temperature monitor in a small-outline 8-pin TDFN package. Communication to the device is accomplished through an I2C interface. The wide power-supply range and minimal power requirement of the device allow for accurate time/temperature measurements in battery-powered applications. The digital thermometer provides 9-bit to 12-bit temperature readings that indicate the temperature of the device. No additional components are required; the device is truly a "temperature-to-digital" converter.
