General  Description
The APA2058 is a stereo fully  di fferential audio power amplifier with stereo Class-AB cap-free headphone driver and LDO available in a TQF N5X5-32A  pins package. The built-in gain setting at  power amplifier can minimize the external component counts.  For the flexible application, the  gain  can  be  set to 4-steps,  10, 12,  15.6,  and  21.6dB by gain  control  pins  (GAIN0  and  GAIN1).  The power a mplifier’ sfully differential architecture provides  high  PSRR,  in creased immunity to noise and RF rectification.
