AD7814属于传感器变送器的温度传感器-模拟数字输出。由亚德诺半导体技术有限公司制造生产的AD7814温度传感器 - 模拟和数字输出模拟和数字输出温度传感器可用于测量环境热能量。特征包括传感器类型、本地感测温度、远程感测温度、输出类型、电源电压和分辨率。传感器类型为模拟本地/远程/红外、模拟数字、本地/远程、数字本地/远程/红外或内部，感应温度范围为 -55°C 至 200°C。

GENERAL DESCRIPTION

The AD7814 is a complete temperature monitoring system in a SOT-23 package or 8-lead MSOP package. It contains a band gap temperature sensor and 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25°C.

The AD7814 has a flexible serial interface that allows easy inter facing 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 AD7814’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, and domestic appliances.
