CXHA3174是一种低功耗的高精度模拟输出CMOS温度传感器。CXHA3174的输出电压与温度成正比。电压温度比约为-11.6mV/℃，电源电压为+2.5V～+5.5V，可在-55℃～+130℃范围内工作，传递函数几乎为线性，在+30℃时精度为±1.5℃。静态电流约为18μa，从而可以忽略自热效应。由于电源电压范围宽，工作温度范围随电源电压而变化。CXHA3174可在-55°C至+130°C的范围内使用，电源电压为2.5V至5.5V。对于2.0V的较低电源电压，CXHA3174可在0°C至+130°C的温度范围内使用。

产品概述 返回TOP
The CXHA3174 is a low-power precision analog output CMOS temperature sensor. The output voltage of CXHA3174 is proportion to temperature. The voltage to temperature ratio is about -11.6mV/°C. The CXHA3174 can operate over a range of -55°C to +130°C with a power supply voltage of +2.5V to +5.5V. The transfer function of CXHA3174 is almost linear, and the accuracy is ±1.5°C at +30°C. The quiescent current of CXHA3174 is about 18μA, so that the self-heating effects can be ignored. Because of the wide supply voltage range, the operating temperature range varies with the voltage supply. The CXHA3174 can be used over a range of -55°C to +130°C with a supply voltage of 2.5V to 5.5V. For lower supply voltage of 2.0V, the CXHA3174 can be used over a temperature range of 0°C to +130°C.
