APA2060
2.4W Stereo Fully Differential Audio Power Amplifier With Stereo Class AB Cap-Free Headphone Driver and LDO
Features
General Description
The APA2060 is a stereo fully differential audio power amplifier with stereo Class-AB cap-free headphone driver and LDO available in a TQFN5X5-32 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, 6, 10, 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 APA2060 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.
