The LM19 is a precision analog output CMOS integrated-circuit
temperature sensor that operates over a −55°C to +130°
C temperature range. The power supply operating range is
+2.4 V to +5.5 V. The transfer function of LM19 is predominately
linear, yet has a slight predictable parabolic curvature.
The accuracy of the LM19 when specified to a parabolic
transfer function is ±2.5°C at an ambient temperature of +30°
C. The temperature error increases linearly and reaches a
maximum of ±3.8°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 +130°C and −55°C. Decreasing the power
supply voltage to 2.4 V changes the negative extreme to
−30°C, while the positive remains at +130°C.
