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.
