Fast Analog-to-Digital Converter (FADC)
User’s Manual 26-46 V2.0, 2007-07
FADC, V2.0
Note: If ENN = 0 and ENP = 0, the channel amplifier is in power-down mode. The
conversion result is not valid in this case.
ENN 3rwEnable Negative Input
This bit enables the voltage measurement on the
FAINxN analog input.
0
B
Analog input FAINxN is high-impedance. The
lower half of the measuring range is not
available.
1
B
Analog input FAINxN line is connected to the
channel amplifier. The lower half of the
measuring range is available.
CALOFF[2:0] [10:8] rw Calibrate Offset
This bit field determines the value applied for the
offset calibration for channel x. The calibrate offset
value is composed by the most significant bit
CALOFF3 and bit field CALOFF[2:0], resulting in a
4-bit bit field CALOFF[3:0].
CALOFF3 12 rw
CALGAIN [14:13] rw Calibrate Gain
This bit field determines the value applied for the
gain calibration for channel x.
0 [7:4], 11,
[31:15]
r Reserved
Read as 0; should be written with 0.
