AK4341
24-bit 192kHz 100dB stereo DAC with 2Vrms Line Driver
The AK4341 is a 192kHz stereo DAC designed for cost sensitive consumer digital audio applications requiring 2Vrms line output. The AK4341 integrates an output buffer which generates 2Vrms output signal directly, and a combination filter of SCF (Switched Cap Filter) and CTF (Continuous Time Filter), which maximizes clock jitter tolerance and suppresses out-band noise. Both of built-in features can reduce external component requirements at digital audio output stage. The AK4341 is available in a 16-pin TSSOP package effective to save footprint.
