Check for Samples: LM45 FEATURES DESCRIPTION The LM45 series are precision integrated-circuit
temperature sensors, whose output voltage is linearly
proportional to the Celsius (Centigrade) temperature.
The LM45 does not require any external calibration or
trimming to provide accuracies of В±2В°C at room
temperature and В±3В°C over a full -20 to +100В°C
temperature range. Low cost is assured by trimming
and calibration at the wafer level. The LM45's low
output impedance, linear output, and precise inherent
calibration make interfacing to readout or control
circuitry especially easy. It can be used with a single
power supply, or with plus and minus supplies. As it
draws only 120 ОјA from its supply, it has very low
self-heating, less than 0.2В°C in still air. The LM45 is
rated to operate over a -20В° to +100В°C temperature
range. 1 2 Calibrated Directly in В° Celsius (Centigrade)
