9 Power Supply Recommendations

Source V+ with an external voltage as recommended in the electrical characteristics table. It is recommended to place a 100nF ceramic bypass capacitor to ground as close to possible to the V+ pin. In addition, an electrolytic or tantalum capacitor of 10μF is recommended. The bulk capacitor does not need to be in close vicinity with the LMP8646 and could be close to the voltage source terminals or at the output of the voltage regulator powering the LMP8646.
