GENERAL DESCRIPTION

The AD7314 is a complete temperature monitoring system in an 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 AD7314 has a flexible serial interface that allows easy interfacing to most microcontrollers. The interface is compat ible with SPI, QSPI?, and MICROWIRE? protocols 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.

PRODUCT HIGHLIGHTS

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 of 2.65 V to 5.5 V.

3. Space-saving 8-lead MSOP package.

4. 10-bit temperature reading to 0.25∞C resolution.

5. The AD7314 features a standby mode that reduces the current consumption to 1 mA max.
