• Manufacturer Part Number: ak5356
• Description: Low Power 20-bit Adc With Mic-amp & Pga
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
n Digital High Pass Filter
The AK5356 has a Digital High Pass Filter (HPF) to cancel DC-offset in both the IPGA and ADC. The cut-off frequency
of the HPF is 3.4Hz at fs=44.1kHz. This cut-off frequency scales with the sampling frequency (fs). And the HPF can select
ON/OFF by HPF bit.
