NOTES
1Temperature Range –40°C to +85°C.
2Guaranteed by design and/or characterization data on production release.
3When a 28.8 kHz crystal is used, normal mode rejection is improved so that the rejection equals 75 dB at 50 ± 1 Hz and equals 66 dB at 60 ± 1 Hz.
4Normal Mode refers to the case where the ADC is running.
