LM20
SNIS106Q –DECEMBER 1999–REVISED JANUARY 2015
LM20 2.4-V, 10-µA, SC70, DSBGA Temperature Sensor

error increases linearly and reaches a maximum of
±2.5°C at the temperature range extremes. The

voltage. At a power supply voltage of 2.7 V to 5.5 V,

the temperature range extremes are 130°C and
• Output Impedance 160 Ω (Maximum)
−55°C. Decreasing the power supply voltage to 2.4 V
changes the negative extreme to −30°C, while the

< 16 μA −2.5 mV (Maximum)
The LM20 quiescent current is less than 10 μA.

Shutdown capability for the LM20 is intrinsic because
• Cellular Phones
its inherent low power consumption allows it to be

powered directly from the output of many logic gates
or does not necessitate shutdown.
