PP, Rev 3.3, September 2012

High Performance Stereo Playback to Line-out - DAC input to LINEOUTL+LINEOUTR or HPOUTL+HPOUTR pins with 10kΩ /

50pF load

Test conditions:

VMID_RES = 01 (for normal operation)

CP_DYN_PWR = 1 (Class-W, Charge pump controlled by real-time audio level)

Low Power Playback mode disabled. (See Table 49 for details; note that Low Power Playback mode is disabled by default.)
