The STLM20 is a precision analog output temperature sensor for low current applications where maximizing battery life is important. It operates over a –55 °C to 130 °C (grade 7) or –40 °C to 85 °C (grade 9) temperature range. The power supply operating range is 2.4 V to 5.5 V. The maximum temperature accuracy of the STLM20 is ± 1.5 °C (±0.5 °C typ) at an ambient temperature of 25 °C and V_CCof 2.7 V. The temperature error increases linearly and reaches a maximum of ±2.5 °C at the temperature range extremes. The temperature range is affected by the power supply voltage. For the temperature grade 7 device, a power supply voltage of 2.7 V to 5.5 V, the temperature range extremes are +130 °C and –55 °C (decreasing the power supply voltage from 2.7 V to 2.4 V changes the low end of the operating temperature range from –55 °C to –30 °C, while the positive remains at +130 °C).

The STLM20 has a maximum quiescent supply current of 8 μA. Therefore, self-heating is negligible.

stlm20是精密模拟输出温度传感器的低电流应用最大化电池的寿命是很重要的。它工作在一个- 55°C至130°C（7级）或- 40°C至85°C（9级）的温度范围。该电源的工作范围为2.4 V至5.5 V的stlm20最高温度精度±1.5°C（±0.5°C型）在环境温度25°C和vccof 2.7 V的温度误差呈线性增加，在极端的温度范围内达到最大的±2.5°C。温度范围受供电电压的影响。对于温度级7级设备，电源电压为2.7伏至5.5伏，温度范围为130°C和55°C（降低电源电压从2.7伏至2.4伏的变化的工作温度范围从- 55摄氏度至- 30°C，而正保持在130°C）。

有一个最大的stlm20静态电源电流8μA.因此，自加热可以忽略不计
