[AK4393] AK4393 Advanced Multi-Bit 96kHz 24-Bit '6 DAC The AK4393 is a high performance stereo DAC for the 96kHz sampling mode of DAT, DVD including a 24bit digital filter. The AK4393 introduces the advanced multi-bit system for '6 modulator. This new architecture achieves the wider dynamic range, while keeping much the same superior distortion characteristics as conventional Single-Bit way. In the AK4393, the analog outputs are filtered in the analog domain by switched-capacitor filter SCF with high tolerance to clock jitter. The analog outputs are full differential output, so the device is suitable for hi-end applications. The operating voltages support analog 5V and digital 3.3V, so it is easy to I/F with 3.3V logic IC. x 128x Oversampling x Sampling Rate up to 108kHz x 24Bit 8x Digital Filter Ripple r0.005dB, Attenuation 75dB x High Tolerance to Clock Jitter x Low Distortion Differential Output x Digital de-emphasis for 32, 48 & 96kHz sampling x Soft Mute x THD+N -100dB x DR, S/N 120dB x I/F format: MSB justified, 16/20/24bit LSB justified, I2S x Master Clock Normal Speed 256fs, 384fs, 512fs or 768fs Double Speed 128fs, 192fs, 256fs or 384fs x Power Supply to 5.25V Analog , 3 to 5.25V Digital x Small Package 28pin SSOP DIF0 DIF1 DIF2 DVDD DVSS DEM0 DEM1 AVDD AVSS LRCK BICK SDATA PDN SMUTE Audio Data Interface De-emphasis Control De-emphasis Soft Mute De-emphasis Soft Mute 8x Interpolator '6 Modulator 8x Interpolator '6 Modulator Control Register Clock Divider BVSS VCOM AOUTL+ AOUTLAOUTR+ AOUTR- CSN CCLK CDTI P/S MCLK CKS0 CKS1 CKS2 VREFH VREFL M0039-E-03 -1- 2012/01 - Ordering Guide AK4393VM -40 ~ +85 qC 28pin SSOP 0.65mm pitch [AK4393] - Pin Layout DVSS DVDD MCLK BICK SDATA LRCK SMUTE/CSN DEM0/CCLK DEM1/CDTI DIF0 DIF1 DIF2 Top View CKS2 CKS1 CKS0 VCOM AOUTL+ AOUTL- AOUTR+ AOUTR- AVSS AVDD VREFH VREFL BVSS M0039-E-03 -2- 2012/01 [AK4393] PIN/FUNCTION No. Pin Name 1 DVSS 2 DVDD 3 MCLK PDN 4 BICK 5 SDATA 6 7 LRCK SMUTE CSN DFS 9 DEM0 10 CCLK DEM1 11 CDTI 12 DIF0 13 DIF1 14 DIF2 15 BVSS 16 VREFL 17 VREFH 18 AVDD 19 AVSS 20 AOUTR21 AOUTR+ 22 AOUTL23 AOUTL+ 24 VCOM 25 P/S Ordering Guide was changed.
