10 Power Supply Recommendations

The DAC161S997 requires a voltage supply within 2.7 V and 3.6 V. Multilayer ceramic bypass X7R capacitors of 0.1μF between the VA and GND pins, and between the VD and GND pins are recommended. If the supply is located more than a few inches from the DAC161S997, additional bulk capacitance may be required in addition to the ceramic bypass capacitors. An electrolytic capacitor with a value of 10μF or 22μF is a typical choice
