STLM20 - Ultra-low Current 2.4V Precision Analog Temperature Sensor

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 accuracy of the STLM20 is ± 1.5°C, at 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 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.

The STLM20W87F is a SOT323 Ultra-low Current 2.4V Precision Analog Temperature Sensor grade 7 (-55 to 130°C) that comes in a 3000 piece reel.
