11 Power Supply Recommendations

For supplying power to the PCA9306-Q1, the VREF1 pin can be connected directly to a power supply. The VREF2 pin must be connected to the VDPU power supply through a 200-kΩ resistor. Failure to have a high impedance resistor between VREF2 and VDPU results in excessive current draw and unreliable device operation.
