SNIS175A – MARCH 2013 – REVISED JANUARY 2015 LMT88 2.4-V, 10-µA, SC-70 Temperature Sensor
1 Features 3 Description The LMT88 device is a precision analog output
CMOS integrated-circuit temperature sensor that
operates over a temperature range of -55В°C to
130В°C . The power supply operating range is 2.4 V to
5.5 V. The transfer function of LMT88 is
predominately linear, yet has a slight predictable
parabolic curvature. The accuracy of the LMT88
when specified to a parabolic transfer function is
typically В±1.5В°C at an ambient temperature of 30В°C.
The temperature error increases linearly and reaches
a maximum of В±2.5В°C at the temperature range
extremes. The temperature range is affected by the
power supply voltage. At a power supply voltage of
2.7 V to 5.5 V, the temperature range extremes are
130В°C and -55В°C. Decreasing the power supply
voltage to 2.4 V changes the negative extreme to …
