Preliminary Technical Data
LAYOUT RECOMMENDATIONS
PARTS PLACEMENT
The ADC input voltage-to-current resistors and the ADC
current set resistor should be placed as close to the input pins
(2, 3 & 4) as possible.
All 100 nF bypass capacitors, which are recommended for every
analog, digital, and PLL power/ground pair, should be placed as
close to the ADAU1701 as possible. Both the 3.3 V and 1.8 V
signals on the board should also each be bypassed with a single
bulk capacitor (10-47 μF).
Rev. PrF | Page 37 of 43
All traces in the crystal oscillator circuit (Figure 16) should be
kept as short as possible to minimize stray capacitance. There
should not be any long board traces connected to any of these
components, as this may affect crystal start-up and operation.
GROUNDING
A single ground plane should be used in the application layout.
Components in an analog signal path should still be placed
away from digital signals.
