GENERAL DESCRIPTION
The AK4201 is an audio stereo cap-less headphone amplifier. The AK4201 eliminates the need for large
DC-blocking capacitors with a built-in Charge-pump circuit. A 100dB PSRR (Power Supply Rejection
Ratio) is achieved by a built-in regulator, and 2Vrms outputs are available with excellent linearity when the
AK4201 is used as a lineout amplifier. The AK4201 is available in tiny 12-pin USON (2.2 X 2.9mm), saving
board space, cost, and reducing component height.
