ASAHI KASEI [AK4351] 18Bit Advanced Multi Bit DS 2ch DAC GENERAL DESCRIPTION The AK4351 is a high cost performance 18bit stereo DAC for low-end digital audio systems. The modulator in the AK4351 uses the new developed Advanced Multi Bit architecture with wide dynamic range. The analog outputs are filtered in the analog domain by a bination of SCF and CTF. Therefore, any external filters are not required. The SCF techniques also improve the loss of accuracy from clock jitter. Therefore, the AK4351 is suitable for the system like STB including PLL circuit. The AK4351 is available in very small 16pin TSSOP package, which reduces system space. Features - Sampling Rate Ranging from 8k Hz to 50k Hz - 128 times Oversampling - Perfect filtering 18bit 8 times FIR Interpolator with 57d B attenuation 2nd order LPF Total Response: ± 0.2d B at 20k Hz - On chip Buffer with Single End Output - Digital de-emphasis for 44.1k Hz sampling - I/F format: MSB justified, 16/18bit LSB...
