AK4388
192kHz 24-Bit 2ch ∆Σ DAC
GENERAL DESCRIPTION
The AK4388 offers the perfect mix for cost and performance based audio systems. Using AKM's multi bit
architecture for its modulator, the AK4388 delivers a wide dynamic range while preserving linearity for
improved THD+N performance. The AK4388 integrates a combination of SCF and CTF filters 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 AK4388 is offered in a
space saving 16pin TSSOP package.

Notes: 9. The passband and stopband frequencies scale with fs(system sampling rate).
For example, PB=0.4535×fs (@±0.05dB), SB=0.546×fs.
10. The calculating delay time which occurred by digital filtering. This time is from setting the 16/24bit data
of both channels to input register to the output of analog signal.
