[AK4432]
AK4432
108dB 192kHz 32bit 2-Channel Audio DAC
1. General Description
The AK4432 is a 32-bit Stereo DAC which corresponds to digital audio systems. An internal circuit
includes newly developed 32-bit Digital Filter achieving short group delay and high quality sound. The
AK4432 has single end SCF outputs, increasing performance for systems with excessive clock jitter. The
AK4432 is ideal for a wide range of applications that demands high sound quality including Home Theater
and Car audio surround systems. It is housed in a 16-pin TSSOP package, saving more board space.
