Space-Saving SOT-23 Package
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 interfacing 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.
PRODUCT HIGHLIGHTSThe 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.
Supply voltage of 2.7 V to 5.5 V
Space-saving 6-lead SOT-23 package and 8-lead MSOP package
10-bit temperature reading to 0.25°C resolution
Standby mode that reduces the current consumption to 1 µA
