1 / 42 page  ASAHI KASEI [AK4620B] MS0401-E-00 2005/07 - 1 - GENERAL DESCRIPTION The AK4620B is a high performance 24-bit CODEC that supports up to 192kHz record and playback. The on-board analog-to-digital converter has a high dynamic range due to AKM’s Enhanced Dual-Bit architecture. The DAC utilizes AKM’s Advanced Multi-Bit architecture that achieves low out-of-band noise and high jitter tolerance through the use of Switched Capacitor Filter (SCF) technology. The AK4620B has an input Programmable Gain Amplifier and is ideal for Pro Audio sound cards, Digital Audio Workstations, DVD-R, hard disk, CD-R recording/playback systems, and musical instrument recording. FEATURES • 24-bit 2-channel ADC - Selectable Single-ended or Differential Input - High Performance Linear Phase Digital Anti-Alias Filter Passband: 0 ~ 20.25kHz (@fs=44.1kHz) Ripple: ± 0.005dB Stopband Attenuation: 100dB - S/(N+D): 90dB (single-ended) 100dB (differential) - S/N: 110dB (single-ended) 113dB (differential) - Digital High-pass Filter for Offset Cancellation - Input PGA: 0dB to +18dB, 0.5dB/step (for single-ended input) - Input Digital Attenuator: 0dB to – 63dB, 0.5dB/step - Overflow Flag - Audio Interface Format: MSB justified or I 2S • 24-bit 2-channel DAC - 24-bit 8 times Oversampling Linear Phase Digital Filter Ripple: ±0.005dB Stopband Attenuation: 75dB - Switched-cap Low Pass Filter - Differential Outputs - S/(N+D): 97dB - S/N: 115dB - De-emphasis for 32kHz, 44.1kHz, 48kHz Sampling - Output Digital Attenuator: Linear 255 steps - Soft Mute - Zero Detection Function - Audio interface format: MSB justified, LSB justified, I 2S, or DSD • High Jitter Tolerance • Sampling Rate: Up to 216kHz • µP Interface: 3-wire Serial Interface • Master Clock - 128fs/192fs/256fs/384fs/512fs/768fs/1024fs • Power Supply: 5V ± 5%(Analog), 3V~3.6V with 5V tolerant I/O(Digital) • Small 30-pin VSOP package • Ta: -10 to 70 °C 24-Bit 192kHz Audio CODEC with IPGA AK4620B |
