• Description: Super High Performance 192kHz 24-Bit ADC
• Manufacturer: AKM [Asahi Kasei Microsystems]

ASAHI KASEI
The AK5394A includes a digital high pass filter for DC offset cancellation. The cut-off frequency of the HPF is 1Hz at
fs=48kHz (Normal Speed Mode), at fs=96kHz (Double Speed Mode), at fs=192kHz (Quad Speed Mode) and also scales
with sampling rate (fs) respectively.
