Other Parts Discussed in Thread: PCM3060
Hi all.
I am currently using a TLVAIC3106 and I measure a digital offset added by the ADC even though input common mode voltage is at 1.35V.
Using the register 12 (set to 0x40 to enable high pass filter) this digital offset is removed.
My question is : as an offset reduces the input analog dynamic range, will the high pass filter allow to regain this loss ?
e.g. :
case 1.
Given all gain are at 0dB :
0.35V = 0x800000
1.35V => 0x000000
2.35V => 0x7FFFFF
case 2.
Given an offset of 0x003000:
0.35V = 0x803000
1.35V = 0x003000
2.3X (< 2.35V) = 0x7FFFFF
If the high pass filter is applied to case 2, will it allow to achieve desired functioning (as in case 1) ?
Thank you.
