GENERAL DESCRIPTION
The AD7814 is a complete temperature monitoring system in a
SOT-23 package or 8-lead MSOP package. It contains a band
gap temperature sensor and 10-bit ADC to monitor and digitize
the temperature reading to a resolution of 0.25癈.
The AD7814 has a flexible serial interface that allows easy inter-
facing to most microcontrollers. The interface is compatible
with SPI
?/DIV>
, QSPI", and MICROWIRE" protocol, and is also
compatible with DSPs. The part features a standby mode that is
controlled via the serial interface.
The AD7814s wide supply voltage range, low supply current,
and SPI-compatible interface make it ideal for a variety of
applications, including personal computers, office equipment,
and domestic appliances.
