ADT7411ARQ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ADT7411ARQ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 ADT74111 combines a 10-bit temperature-to-digital converter and a 10-bit 8-channel ADC in a 16-lead QSOP. This includes a band gap temperature sensor and a 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25°C. The ADT7411 operates from a single 2.7 V to 5.5 V supply. The input voltage on the ADC channels has a range of 0 V to 2.25 V and the input bandwidth is dc. The reference for the ADC channels is derived internally. The ADT7411 provides two serial interface options: a 4-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP interface standards, and a 2-wire SMBus/I2C interface. It features a standby mode that is controlled via the serial interface.

The ADT7411’s wide supply voltage range, low supply current, and SPI-/I2C-compatible interface make it ideal for a variety of applications, including PCs, office equipment, and domestic appliances.
