| ASAHI KASEI [AK5385A] AK5385A 24Bit 192kHz ADC The AK5385A is a 24bit, 192kHz sampling 2ch A/D converter for high-end audio system. The modulator in the AK5385A uses the Enhanced Dual Bit architecture and the AK5385A realizes high accuracy and low cost. The AK5385A performs 114dB dynamic range, so the device is suitable for AV-amp, AV recorder and musical instruments. The AK5385A is available in 28pin VSOP and SOP package, utilizing less board space. p Sampling Rate 8kHz ~ 216kHz p Full Differential Inputs p S/ N+D 103dB p DR 114dB p S/N 114dB p High Performance Linear Phase Digital Anti-Alias filter • Passband 0~21.768kHz • Ripple 0.005dB • Stopband 100dB p Digital HPF p Power Supply 5V ± 5% Analog , ~ 5.25V Digital p Power Dissipation 183mW p Package 28pin SOP / 28pin VSOP p AK5383/AK5393/AK5394A Semi-Pin compatible VCOM OVF M/S DFS1 DFS0 CKS1 CKS0 PDN VREFL LIN+ LIN- Delta-Sigma Modulator RIN+ RINVREFR Delta-Sigma Modulator Decimation Filter Decimation Filter Audio I/F Controller LRCK BICK MCLK SDTO TEST AVDD AVSS DVDD DVSS BVSS DIF HPFE Block diagram MS0265-E-01 -1- 2003/11 ASAHI KASEI n Ordering Guide AK5385AVS AK5385AVF AKD5385A n Pin Layout VREFL AVSS VCOM LIN+ LINCKS0 DVDD DVSS OVF PDN DIF M/S LRCK BICK [AK5385A] ~ +70°C 28pin SOP 1.27mm pitch ~ +85°C 28pin VSOP 0.65mm pitch Evaluation Board for AK5385A Top View 28 VREFR 27 AVSS 26 TEST 25 RIN+ 24 RIN23 AVDD 22 AVSS 21 BVSS 20 DFS1 19 HPFE 18 DFS0 17 MCLK 16 CKS1 15 SDTO MS0265-E-01 -2- 2003/11 ASAHI KASEI n Compatibility with AK5383/AK5394A Pin 1 Pin 2 Pin 3 Pin 6 Pin 9 Pin 11 Pin 12 Pin 16 Pin 18 Pin 20 Pin 26 Pin 27 Pin 28 fs MCLK at 48kHz MCLK at 96kHz MCLK at 192kHz DR, S/N Input Voltage Offset Calibration AK5385A VREFL AVSS VCOM CKS0 OVF DIF M/S CKS1 DFS0 DFS1 TEST AVSS VREFR 8kHz ~ 216kHz 256/384/512fs 256fs 128fs 114dB ±2.9Vpp Not Available AK5383 VREFL GNDL VCOML ZCAL CAL SMODE2 SMODE1 FSYNC DFS TEST VCOMR GNDR VREFR 1kHz ~ 108kHz 256fs 128fs Not Available 110dB ±2.45Vpp Available AK5394A VREFL+ VREFL− VCOML ZCAL CAL SMODE2 SMODE1 FSYNC DFS0 DFS1 VCOMR VREFR− VREFR+ 1kHz ~ 216kHz 256fs 128fs 64fs 123dB ±2.4Vpp Available [AK5385A] MS0265-E-01 -3- 2003/11 ASAHI KASEI [AK5385A] n Compare PCB layout example between AK5385A and AK5383 Analog Ground 10µ 1 VREFL VREFR 28 10µ 2 GNDL GNDR 27 3 VCOML 4 AINL+ 5 AINL- ~ 5.25V Digital 6 ZCAL 7 VD 8 DGND |
