To enable the output drivers to deliver higher output power, the DAC output swing should be set to its highest level by setting
BITD10D9/REG06H/Page2 to 11. It is possible to increase power even further by disabling the built-in short-circuit
protection by programming bit D8 of Reg1DH/Page2 to 1. In this case care must be taken so a short-circuit at the output
does not occur. Figure 31 shows a typical jack configuration using a capless output configuration. In this configuration, the
TSC2100 drives the loudspeaker whenever headphones are not inserted in the jack and drives the headphones whenever
it is inserted in the jack.
