APA2058 2.4W Stereo Fully Differential Audio Power Amplifier With Stereo Class AB Cap-free Headphone Driver and LDO Features General Description The APA2058 is a stereo fully differential audio power amplifier with stereo Class-AB cap-free headphone driver and LDO available in a TQFN5X5-32A 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 amplifier’ s fully differential architecture provides high PSRR, increased immunity to noise and RF rectification. The APA2058 power amplifiers are capable of driving 2.4W at VDD=5V into 4Ω speaker, the cap-free headphone drivers can provide 180mW at HV DD=3.
