AK4360 Datasheet | Asahi Kasei Microdevices

DESCRIPTION The AK4360 is a 20bit low voltage & power DAC with Headphone Amplifier for digital audio system. The AK4360 uses the new developed Multi-Bit ∆Σ architecture, this new architecture achieves S/N=92d B at low voltage operation. The AK4360 integrates SCF increasing performance for systems with excessive clock jitter. The low power and small package make this point ideal for the portable audio system like MD, MP3, etc. FEATURES - Advanced Multi-Bit ∆Σ DAC - Sampling Rate Ranging: 8k Hz ∼ 50k Hz - On chip perfect filtering 8 times FIR interpolator - Digital de-emphasis for 44.1k Hz sampling - Master clock: 256fs or 384fs - Digital Audio I/F Format: 2’s pliment, MSB first - 20bit I2S or 16bit LSB justified - THD+N: -48d B (-11d B output) - D-Range, S/N: 92d B - Low Frequency Boost Function - Click Noise Free Circuit - On chip Headphone Amplifier - 6.5m W x 2ch@16Ω (THD+N = 10%, HPVCC = 1.2V) - Low Voltage Operation: DAC: 2V (1.8V∼3.3V), HP-AMP: 1.2V (0.9V∼3.3V) - Low power Dissipation: 12m W - Ta = -10 ∼ 70°C - Small Package: 24pin VSOP HPVCC HPGND BICK LRCK SDATA Audio I/F De-emphasis Control Voltage Reference VREF V BOOST VDD VSS Low Freq Boost 8X Interpolator 8X Interpolator ∆Σ Modulator ∆Σ Modulator HP-AMP HP-AMP Clock...
