The AD7314 is a complete temperature monitoring system in 1. The AD7314 has an on-chip temperature sensor that allows an 8-lead MSOP package. It contains a band gap temperature an accurate measurement of the ambient temperature. The sensor and 10-bit ADC to monitor and digitize the temperature measurable temperature range is –35∞C to +85∞C, with a reading to a resolution of 0.25∞C. ±2∞C temperature accuracy. The AD7314 has a flexible serial interface that allows easy 2. Supply voltage of 2.65 V to 5.5 V. interfacing to most microcontrollers. The interface is compat- 3. Space-saving 8-lead MSOP package. ible with SPI, QSPI™, and MICROWIRE™ protocols and is also compatible with DSPs. The part features a standby mode 4. 10-bit temperature reading to 0.25∞C resolution. that is controlled via the serial interface. 5. The AD7314 features a standby mode that reduces the The AD7314’s low supply current and SPI compatible interface current consumption to 1 mA max. make it ideal for a variety of applications, including personal computers, office equipment, and domestic appliances.
