The ADT7301 is a complete temperature monitoring system available in SOT-23 and MSOP packages. It contains a band gap temperature sensor and a 13-bit ADC to monitor and digitize the temperature reading to a resolution of 0.03125°C. The ADT7301 has a flexible serial interface that allows easy interfacing to most microcontrollers. The interface is compatible with SPI?， QSPI?， and MICROWIRE? protocols as well as DSPs. The part features a standby mode that is controlled via the serial interface. The ADT7301’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， automotive， and domestic appliances. The ADT7301 is rated for operation over the ?40°C to +150°C temperature range. It is not recommended to operate the device at temperatures above +125°C for greater than a total of 5% （5，000 hours） of the lifetime of the device. Exposure beyond this limit affects device reliability.
