Hi team,
- is that the maximum SNR is 108dB when PFR=1600Hz, DR=50Hz, signal current=16uA? Is that signal current more than 16uA, the SNR will be higher?
- How much is the SNR nyquist if there has？
- Is that power consumption is RX_SUP current+ IO_SUP current+ TX_SUP current= 21+1+1.5=23.5uA?
- About hardware shutdown's power consumption, it shows RX_SUP current+ IO_SUP current+ TX_SUP current< 1uA, but is there any more detail data, such as <2uA or <1uA to make sure this device is more competitive.
- About DC Ambient Rejection, is there the data of 120Hz？
