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 2.4 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 VCC of 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.
