The common 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 VS1011e 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 on load

resistance.

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).
