Tel: 781/329-4700 www.analog.com Fax: 781/326-8703 © Analog Devices, Inc., 2001 Low-Voltage, 10-Bit Digital Temperature Sensor in 8-Lead SOIC FUNCTIONAL BLOCK DIAGRAM FEATURES 10-Bit Temperature-to-Digital Converter –35 C to +85 C Operating Temperature Range 2 C Accuracy SPI™- and DSP-Compatible Serial Interface Shutdown Mode Space-Saving SOIC Package APPLICATIONS Hard Disk Drives Personal Computers Electronic Test Equipment Office Equipment Domestic Appliances Process Control Mobile Phones GENERAL DESCRIPTION The AD7314 is a complete temperature monitoring system in an 8-lead µSOIC 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 compat- ible 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. 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 2.9 V. 3. Space-saving 8-lead µSOIC 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 µA max. SPI is a trademark of Motorola, Inc. MICROWIRE is a trademark of National Semiconductor Corporation.
