ST STLM20DD9F

The STLM20 is a precision analog output temperature sensor for low current applications where maximizing battery life is important. It operates over a - 55℃ to 130℃ grade 7 or - 40℃ to 85℃ (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℃ (±0.5℃ typ) at an ambient temperature of 25℃ and VCC of 2.7 V. The temperature error increases linearly and reaches a maximum of ±2.5℃ 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℃ and - 55℃ (decreasing the power supply voltage from 2.7 V to 2.4 V changes the low end of the operating temperature range from - 55℃ to - 30℃, while the positive remains at +130℃. The STLM20 has a maximum quiescent supply current of 8μA. Therefore, self - heating is negligible.
