AK4353
96kHz 24Bit ∆Σ DAC with DIT
GENERAL DESCRIPTION
The AK4353 is a stereo CMOS D/A Converter and Digital Audio Interface Transmitter. The DAC signal
outputs are single-ended and are analog filtered to remove out of band noise. Therefore no external filters
are required. The AK4353 can operate at the power supply from 2.7V to 5.5V and the digital I/F can
correspond to both TTL and CMOS levels.
FEATURES
o Stereo ∆Σ DAC
o S/(N+D): 90dB@5V
o DR: 102dB@5V
o S/N:
102dB@5V
o Sampling Speed: 16kHz∼96kHz
o Multiple Master Clock Frequencies:
256fs/384fs/512fs/768fs/1024fs/1536fs for Half speed (16kHz∼24kHz)
256fs/384fs/512fs/768fs
for Normal speed (32kHz∼48kHz)
128fs/192fs/256fs/384fs
for Double speed (64kHz∼96kHz)
o Data Input Formats:
LSB justified / MSB justified / I2S selectable
o Selectable Function:
Soft Mute
Digital Attenuator (256 Steps)
Digital De-emphasis (44.1kHz/48kHz/32kHz)
o Output Mode: Stereo, Mono, Reverse, Mute
o On-Chip Digital Audio Interface Transmitter:
Compatible with S/PDIF, IEC958, AES/EBU
& EIAJ CP1201 consumer mode
o Input Level: TTL/CMOS Selectable
o Output Level: 3.0Vpp@5V
o Control mode: 3-wire Serial / I2C Bus
o Low Power Dissipation: 80mW@5V
o Small 24pin VSOP Package
o Power Supply: 2.7∼5.5V
o Ta: -40∼85°C
