The ADT7301ARMZ-REEL7 is a complete temperature monitoring system 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 ADT7301ARMZ-REEL7 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 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.TheADT7301ARMZ-REEL7 is rated for operation over the −40°C to +150°Ctemperature range. It is not recommended to operate the deviceat temperatures above +125°C for greater than a total of 5% (5,000 hours) of the lifetime of the device. Exposure beyond thislimit affects device reliability.
