POWER REQUIREMENTS

Note 1: The supply currents indicated are the maximum quiescent current of the supply rails. For overall full load or short circuit current specifications, refer to the datasheets of the signal chain components.
Note 2: The supply voltages indicated are the values for typical applications.
Note 3: Consult the corresponding datasheets for details on power dissipation if needed.
Note 4: The actual supply current requirement shall be multiplied depending on the number of channels on the signal chain.
