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.
