GENERAL DESCRIPTION
The AD7814 is a complete temperature monitoring system in
an SOT-23 package or 8-lead
μ
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 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 ap-
plications, including personal computers, office equipment, and
domestic appliances.

MICROWIRE is a trademark of National Semiconductor, Inc.
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
μ
SOIC
package.
4. 10-bit temperature reading to +0.25
°
C resolution.
5. The AD7814 features a standby mode that reduces the
current consumption to 1
μ
A.
