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 MICRO-WIRE 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.
