LM26是一款精密的单数字输出低功耗恒温器,由内部基准电压源,DAC,温度传感器和比较器组成。利用工厂编程,它可以制造出不同的跳变点以及不同的数字输出功能。跳闸点(T OS )可在出厂时预设为-55°C至110°C范围内的任何温度,增量为1°C。 LM26有一个数字输出(OS / OS /US / US ),一个数字输出输入(HYST)和一个模拟输出(V TEMP )。数字输出级可以预设为漏极开路或推挽式。此外,它可以在工厂编程为高电平有效或低电平有效。数字输出可在工厂编程,以指示过温关闭事件(OS或 OS )或欠温停机事件(US或 US )。当预设为过热关闭( OS )时,它将变为低电平,表示芯片温度超过内部预设的T OS 并且当温度低于(T OS -T HYST )时变为高电平。类似地,当预编程为低温停机(美国)时,它将变为高电平表示温度低于T US ,当温度高于(T US +时,变为低电平Ť<子> HYST )。典型的迟滞T HYST 可以设置为2°C或10°C,并由HYST引脚的状态控制。 AV TEMP 模拟输出提供与温度成比例的电压,输出斜率为-10.82 mV /°C。
