GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
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 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.
1. The AD7314 has an on-chip temperature sensor that allows an accurate measurement of the ambient temperature. The measurable temperature range is –35°C to +85°C, with a ± 2°C temperature accuracy. 2. Supply voltage o……
