Overview
ASAHI KASEI [AK4520A] AK4520A 100dB 20Bit Stereo ∆Σ ADC & DAC General Description The AK4520 is a stereo CMOS A/D & D/A converter for middle-range MD/DAT, Surround System and musical instruments.
Signal inputs and outputs are single-ended.
The DAC outputs are analog filtered to remove out of band noise.
External components are minimized.
Features † ∆Σ Stereo ADC - 64x Oversampling - S/(N+D): 90dB at 5V, 86dB at 3V - Dynamic Range: 100dB at 5V, 96dB at 3V - S/N: 100dB at 5V, 96dB at 3V - Digital HPF for offset cancel † ∆Σ Stereo DAC - 128x Oversampling - 2nd order SCF + 2nd order CTF - Digital de-emphasis for 32kHz, 44.
1kHz, 48kHz sampling - S/(N+D): 90dB at 5V, 90dB at 3V - Dynamic Range:...
