Hi All,
Would you mind if we ask AFE7222?
In case of out use ADC_B, as our recognition, ADC_B input pins that are not used can be left un-connected.
And we are not using channel B, power down this channel through SPI.
<Question>
The datasheet(on Address 0x167) says that "if any of the digital features(like interpolation, Fine mixer,
Coarse mixer, or GMC gain/phase or offset) are enabled, then the channelX can be independently powered down
using bits RX_CHA_PDN and RX_CHA_PDNSRC."
So, in order to power down independtly, should we set any digital features?
Only using bits RX_CHA_PDN and RX_CHA_PDNSRC, can we power down CHAX, or not?
Kind regards,
