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, 4 mA and 0.8V, respectively, the error amounts to 0.544°C for

the SOIC.

2:

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
