ADT7301

13位， 0.5C准确，微功耗数字温度传感器，采用6引脚SOT -23 13-Bit, 0.5C Accurate, MicroPower Digital Temperature Sensor in 6-Lead SOT-23

Product Details

The 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 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. 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.
