GENERAL DESCRIPTION                                                   FEATURES

The   PT5322   is   a   dual   bridge-connected   audio   power        P  @1% THD+N:
                                                                             O

amplifier   which,   when   connected   to   a   5V  supply,   will        3?, 4? loads:      2.2W (typ), 2.0W (typ)
deliver 2.1W to a 4? load or 2.4W to a 3? load with                         8? load:     1.3W (typ)
less   than  1.0%    THD+N.     In  addition,   the  headphone         SE modeTHD+N@75mWinto 32?: 0.01%(max)
                                                                       Shutdown current:             0.7µA (typ)
input     pin   allows    the   amplifiers     to  operate     in
                                                                       Supply voltage range:            2.5V to 5.5V
single-ended mode when driving stereo headphones.
                                                                      PSRR@217Hz:              80dB (typ)
The PT5322 has a HP (headphone) enable input, which                    Stereo headphone amplifier mode
activates the single ended headphone mode and disables                 “Click and pop” suppression circuitry
