Decoupling and Layout Methodology for Wolfson DACs, ADCs and CODECs
This application note looks at the general decoupling and layout practice required for Wolfson converters to achieve maximum performance in a typical high-speed mixed-signal circuit.
APPLICATION
Wolfson DACs, ADCs and CODECs have both digital and analogue interfaces. It is important that noise is minimised to get the maximum converter performance. In our datasheets there are a number of supply pins on each chip. They are labelled according to their internal connection, not necessarily how they should be connected externally. The datasheets show typical supply connections and decoupling arrangements and this report goes into further details.
