AK4522 - 20-BIT STEREO ADC/DAC

General Description

The AK4522 has a dynamic range of 100dB and is well-suited middle-range MD, surround system, musical instruments and car audio.

Signal inputs and outputs are single-ended.

The DAC outputs are analog filtered to remove out of band noise.

Key Features

  • ΔΣ Stereo ADC - 64x Oversampling - Sampling Rate Ranging from 16kHz to 48kHz - S/(N+D): 92dB - Dynamic Range, S/N: 100dB - Digital HPF for offset cancellation.
  • ΔΣ Stereo DAC - 128x Oversampling - Sampling Rate Ranging from 16kHz to 48kHz - 2nd order SCF + 2nd order CTF - Digital de-emphasis for 32kHz, 44.1kHz, 48kHz sampling - S/(N+D): 90dB - Dynamic Range, S/N: 100dB - Soft Mute.
  • High Jitter Tolerance.
  • Master Clock: 256fs, 384fs, 512fs.

ASAHI KASEI [AK4522] AK4522 20Bit Stereo ΔΣ ADC & DAC GENERAL DESCRIPTION The AK4522 has a dynamic range of 100dB and is well-suited middle-range MD, surround system, musical instruments and car audio. Signal inputs and outputs are single-ended. The DAC outputs are analog filtered to remove out of band noise. External components are minimized. The AK4522 is available in a small 24pin SSOP package, which will reduce system space. FEATURES • ΔΣ Stereo ADC - 64x Oversampling - Sampling Rate Ranging from 16kHz to 48kHz - S/(N+D): 92dB - Dynamic Range, S/N: 100dB - Digital HPF for offset cancellation • ΔΣ Stereo DAC - 128x Oversampling - Sampling Rate Ranging from 16kHz to 48kHz - 2nd order SCF + 2nd order CTF - Digital de-emphasis for 32kHz, 44.
