Overview
CONFIDENTIAL [AK4201] = Preliminary = AK4201 Stereo Cap-less HP-Amp 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.
The PSRR (Power supply Rejection Ratio) can achieve to 100dB with a built-in regulator, and it can output 2Vrms with excellent linearity when used as lineout amplifier.
The AK4201 is available in tiny 12-pin USON (2.
2 X 2.
9mm), saving board space, cost, and component height.
FEATURE † Stereo Cap-less Amplifier (No DC-blocking capacitors required) † High PSRR (100dB at 217Hz) † Output Power: 65 mW x 2ch @ 16Ω, AVDD=PVDD=5.
0V, THD+N=-40dB 30 mW ...
