2.4V,10uA ANALOG
TEMPERATURE SENSOR
temperature sensor that operates over a supply voltage range from
2.4V to 5.5V, with a current consumption of only 10µA (max).
because minimizing battery cost and maximizing useful battery life
are crucial.
to temperature. Accuracy is ±1.5°C (max) at an ambient temperature
of +30˚C.The temperature error increases linearly and reaches a
maximum of ±2.5˚C at the temperature range extremes. Self-heating
effects are negligible (less than 0.02˚C in still air) due to the low
current consumption.
supply. The UTC TS20 can be used over a range of -55°C to +130°C
with a supply voltage of 2.7V to 5.5V.For applications with a supply
voltage of 2.4V, the UTC TS20 can be used over a temperature
range of -30°C to +130°C.
