Summary description

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 2.4V to 5.5V. The accuracy of the STLM20 is ± 1.5°C, at an ambient temperature of 25°C. 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 2.7V to 5.5V, the temperature range extremes are +130°C and –55°C. Decreasing the power supply voltage to 2.4V changes the negative extreme to –30°C, while the positive remains at +130°C.

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