PCM1840: HPF cut off frequency

Hanno Reimer

Part Number: PCM1840
Other Parts Discussed in Thread: TLV320ADC6140

any chance to lower the HPF cut off of PCM1840 or to switch off the HPF? 24Hz @96KHz and 48Hz @192KHz hurts within high-end audio amps!

Hi Hanno,

The HPF for PCM1840 is fixed at 0.00025*fs and since this is a HW controlled device with small area it unfortunately is not configurable. If you need similar performance with the option to program this I would suggest TLV320ADC6140.

Best,

Zak
