With AGC at
3 dB, U full ADC range is obtained at V
i
= 1.89 V; with AGC at +6 dB, U full ADC range is obtained at
V
i
= 0.67 V; with AGC at
3 dB, V full ADC range is obtained at V
i
= 1.48 V; with AGC at +6 dB, V full ADC range is
obtained at V
i
= 0.52 V.

which are major load frequencies: SVR is relative variation of the full scale analog input for a supply
variation of 0.25 V.
The AC characteristics are in accordance with the I
2
C-bus specification for fast mode (clock frequency maximum
400 kHz). Information about the I
2
C-bus can be found in the brochure “I
2
C-bus and how to use it”(order number
9398 393 40011).
More information about the SNERT-bus protocol can be found in Application Note “The SNERT-bus specification”
(AN95127).
