Features: The AD7314 is a complete temperature monitoring system in an 8-lead SOIC package. It contains a bandgap temperature sensor and 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25°C.
The AD7314 has a flexible serial interface that allows easy interfacing to most microcontrollers. The interface is compatible with SPI, QSPI and MICROWIRE(TM) protocol and is also compatible with DSPs. The part features a standby mode that is controlled via the serial interface.
The AD7314's low supply current and SPI-compatible interface, make it ideal for a variety of applications, including personal computers, office equipment, and domestic appliances.
