Note
1:
Output current should be minimized for best temperature accuracy. Power dissipation within the TCN75 will cause self-heating and
temperature drift. At maximum rated output current and saturation voltage, 4mA and 0.8V, respectively, the error amounts to 0.544°C for
the SOIC.
All part types of the TCN75 will operate properly over the wider power supply range of 2.7V to 5.5V. Each part type is tested and specified
for rated accuracy at its nominal supply voltage. As V
DD
varies from the nominal value, accuracy will degrade 1°C/V of V
DD
change.
