ADT7301: 13-Bit, ±1ºC Accurate, MicroPower Digital Temperature Sensor in 6-Lead SOT-23 and 8-Lead MSOP
Product Description
The ADT7301 is a complete temperature monitoring system in SOT-23 and MSOP packages. It contains a bandgap 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™ 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.
