illustrate

该LM94022是一款高精度模拟输出CMOS集成电路温度传感器，在高达1.5伏特低电源电压工作。 AB类输出结构使LM94022强大的输出源和汇的驱动重负载电流能力。 例如，它非常适合于源的采样和保持模拟到数字转换器，其输入的瞬态负载要求。 虽然在宽温度范围为-50 ° C至+150经营℃，LM94022提供了一个输出电压成反比porportional来测量温度。 而LM94022的低电源电流使电池供电系统，以及一般温度传感应用的理想选择。

两个逻辑输入，增益选择1（GS1）和增益选择0（GS0），选择的温度到电压输出的传递函数的增益。 四个斜坡选择：-5.5毫伏/ ° C，-8.2毫伏/ ° C，-10.9毫伏/ ° C和-13.6毫伏/ ° C。 在最低增益配置（GS1和GS0都绑低），可以操作的LM94022与1.5V供应，同时测量在整个-50 ° C至+150 ° C的工作温度范围。 绑两个输入高导致传递函数有最大的-13.6毫伏/ ° C的最高温度灵敏度增益。 The gain select input can be connected directly to VDD或地面没有任何上拉或下拉电阻，减少元件数量和电路板面积。 这些投入也可带动逻辑使系统在运行过程中优化系统诊断或增益的信号。
