Table 73 Headphone PGA and Speaker PGA Volume Range

SPEAKER OUTPUT CONFIGURATIONS

The speaker outputs SPKOUT are driven by the two speaker PGAs SPKOUTL and SPKOUTR. Fine

volume control is available on the speaker paths using the SPKOUTL_VOL and SPKOUTR_VOL

PGAs. A volume boost function (CLASSD_VOL) is available on both the speaker paths.

The speaker outputs SPKOUTL and SPKOUTR operate in a BTL configuration in Class D amplifier

mode. The speaker outputs are capable of supporting up to 1W per channel into stereo 8

 BTL loads,

or 2W into a mono 4

 BTL load.

The connections for stereo and mono speaker configurations are shown in Figure 34
