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
°C.
The AD7814 has a flexible serial interface that allows easy inter-
facing to most microcontrollers. The interface is compatible
with SPI
, QSPI, and MICROWIRE protocol, and is also
compatible with DSPs. The part features a standby mode that is
controlled via the serial interface.
The AD7814’s 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.

Patent Rights to use these components in an I
2C system, provided that the system
conforms to the I
2C Standard Specification as defined by Philips.
PRODUCT HIGHLIGHTS
1. The AD7814 has an on-chip temperature sensor that allows
an accurate measurement of the ambient temperature. The
measurable temperature range is –55
°C to +125°C, with a
±2°C temperature accuracy.
2. Supply voltage of 2.7 V to 5.5 V
3. Space-saving 6-lead SOT-23 package and 8-lead MSOP
package
4. 10-bit temperature reading to 0.25
°C resolution
5. Standby mode that reduces the current consumption to 1
