I have a problem using the tlv320adc6140. I want to acquire dc wave, how to set the registers to bypass the HPF in data chain?
Hi,
The HPF can be bypassed by writing 0 into the HPF_SEL[1:0] bits in page 0 register 0x6B when configuring the device.
Thanks and Regards,

Hi
I have tried to write 0 into the HPF_SEL[1:0] bits in page 0 register 0x6B, but it does't work. Is there any other register I should write to acquire a DC voltage? The input side circuit has been set as DC coupled.
Hi,
Can you provide the sequence of I2C writes that are being done (including the HPF_SEL) prior to powering up the ADC?
Thanks and Regards,
