    ... DESIGN AND LAYOUT CONSIDERATIONS Power-Supply Pins (VCCAD1/2, VCCDA1/2, and VDD1/2) The digital and analog power-supply pins of the PCM3168A and PCM3168A-Q1 should be bypassed to the corresponding ground pins with 1- F ceramic capacitors placed as close to the pins as possible. Each power-supply line (VCC, VDD) to the PCM3168A and PCM3168A-Q1 should be bypassed to the corresponding ground pins with 10- F electrolytic capacitors to maximize the dynamic performance of the ADC and DAC ...
