AK4524 is a 24bit 96kHz audio codec produced by Asahi Kasei. The chip has an enhanced dual-bit architecture ADC with a wide dynamic range and uses SCF technology to achieve low output noise and high jitter tolerance. AK4524 also has an input PGA and is suitable for MD, DVTR systems and musical instruments.
The AK4524 is a high performance 24bit CODEC designed for the 96kHz recording system. The ADC utilizes an Enhanced Dual Bit architecture with wide dynamic range, while the DAC employs a new Advanced Multi Bit architecture to achieve low outband noise and high jitter tolerance using SCF (switched capacitor filter) techniques.
Key features include a 24-bit 2-channel ADC with 64x oversampling and an input PGA providing up to +18dB gain, alongside a 24-bit 2-channel DAC with 128x oversampling. The device supports MSB justified or I²S formats for both ADC and DAC interfaces and operates on a 5V power supply.
