The ground buffer GBUF can be used for common voltage (1.23 V) for earphones. This will eliminate
the need for large isolation capacitors on line outputs, and thus the audio output pins from VS1002d may
be connected directly to the earphone connector.
If GBUF is not used, LEFT and RIGHT must be provided with 1-100 µF capacitors depending load
resistance.
If UART is not used, RX should connect to DVDD and TX be unconnected.
Note: This connection assumes SM SDINEW is active (see Chapter 8.6.1). If also SM SDISHARE is
used, xDCS should have a pull-up resistor (see Chapter 7.2.1).
