8.2.1.3 Application Curve

The TMP61 accuracy varies depending on the selected biasing circuit. This variation can be seen in Figure 8-13. VTEMP is shown with either VBIAS at 2 V in a resistor divider circuit (RBIAS = 10 kΩ ±1%) or IBIAS at 200 µA. Supply sources used are assumed to be ideal. The best accuracy is achieved using a direct current bias method.
