ADT7420UCPZ-RL7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ADT7420UCPZ-RL7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 ADT7420 is a high accuracy digital temperature sensor offering breakthrough performance over a wide industrial range, housed in an LFCSP package. It contains a band gap temperature reference and a 13-bit ADC to monitor and digitize the temperature to a 0.0625°C resolution. The ADC resolution, by default, is set to 13 bits (0.0625°C). This can be changed to 16 bits (0.0078°C) by setting Bit 7 in the configuration register to 1 (Register Address 0x03).
