Description:
Reading returns a list with the possible filter modes.
- "sinc4" - Sinc 4. Excellent noise performance. Long 1st
- conversion time. No natural 50/60Hz rejection.
- "sinc4+sinc1" - Sinc4 + averaging by 8. Low 1st conversion time.
- "sinc3" - Sinc3. Moderate 1st conversion time. Good noise
- performance.
- "sinc3+rej60" - Sinc3 + 60Hz rejection. At a sampling frequency
- of 50Hz, achieves simultaneous 50Hz and 60Hz
- rejection.
- "sinc3+sinc1" - Sinc3 + averaging by 8. Low 1st conversion time.
- Best used with a sampling frequency of at least
- 216.19Hz.
- "sinc3+pf1" - Sinc3 + Post Filter 1.
- 53dB rejection @ 50Hz, 58dB rejection @ 60Hz.
- "sinc3+pf2" - Sinc3 + Post Filter 2.
- 70dB rejection @ 50Hz, 70dB rejection @ 60Hz.
- "sinc3+pf3" - Sinc3 + Post Filter 3.
- 99dB rejection @ 50Hz, 103dB rejection @ 60Hz.
- "sinc3+pf4" - Sinc3 + Post Filter 4.
- 103dB rejection @ 50Hz, 109dB rejection @ 60Hz.
