AK4381VT

108dB 192kHz 24Bit 2CH DAC

GENERALDESCRIPTION

The AK4381offers the perfect mix for cost and performance based audio systems. Using AKM"s multi bit

architecture for its modulator the AK4381 delivers a wide dynamic range while preserving linearity for

improved THD+N performance. The AK4381 has  full differential  SCF outputs, removing the need for AC

coupling capacitors and increasing performance for systems with excessive clock jitter. The 24 Bit word

length and 192kHz sampling rate make this part ideal for a wide range of applications including DVD-Audio. The AK4381 is offered in a space saving 16pin TSSOP package.
