Product Details

The AD7314 is a complete temperature monitoring system in an 8-pin µSOIC package. It contains a bandgap temperature sensor and 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25ºC.

The AD7314 has a flexible serial interface that allows easy interfacing to most microcontrollers. The interface is compatible with SPI, QSPI and MICROWIRE protocol and is also compatible with DSPs. It is pin compatible with the Dallas DS1722 part.

The part features a standby mode, which is controlled via the serial interface. The AD7314 has a supply voltage range of +2.65 V to +2.9 V. Having a very low supply current and SPI compatible interface, the AD7314 is ideal for a variety of applications, including personal computers, office equipment and domestic appliances.


  1. The AD7314 has an on-chip temperature sensor that allows an accurate measurement of the ambient temperature. The measurable temperature range is –35°C to +85°C, with a ±2°C temperature accuracy.
  2. Supply voltage of 2.65 V to 5.5 V.
  3. Space-saving 8-lead MSOP package.
  4. 10-bit temperature reading to 0.25°C resolution.
  5. The AD7314 features a standby mode that reduces the current consumption to 1 mA max.
