Bypass_mux (4 bits)
These bits enable the possibility to bypass the digital 4 to 1 multi-
plexer.
0000: no bypass (default)
PGA_SETTING <11:0>
This register defines all parameters to set the PGA. The register
consists of different "sub-registers"
Gain_pga (4 bits)
These bits set the gain of the PGA. The following
an overview of the different gain settings.
Table 14.
Unity_pga (1 bit)
This bit sets the PGA in unity amplification.
0: No unity amplification, gain settings apply
1: Unity gain amplification, gain setting are ignored (default)

Sel_uni (1 bit)
This bit selects whether or not the signal gets a 0.5 amplification
before the PGA.
0: amplification of 0.5 before PGA
1: Unity feed through (default)
Enable_analog_in (1 bit)
This bit enables/disables an analog input to the PGA.
0: analog input disabled (default)
1: analog input enabled
Enable_adc (4 bits)
These bits can separately enable/disable the different ADCs.
0000: No ADCs enabled
1111: All ADCs enabled (default)
0001: ADC 1 enabled
0010: ADC 2 enabled
Sel_calib_fast (1 bit)
Selects the fast/slow calibration of the ADC
0: slow calibration
1: fast calibration
2ADC Calibration Word <32:0>
The calibration word for the ADCs is distributed over three
registers (13, 14 and 15). These registers all have their default
value and changing this value is not recommended. The default
register values are:
calib_adc<11:0>: 101011011111
calib_adc<23:12>: 011011011011
calib_adc<32:24>: 000011011011
Data Interface (SPI)
The serial-3-wire interface (or Serial-to-Parallel Interface) uses a
serial input to shift the data in the register buffer. When the
complete data word is shifted into the register buffer the data
word is loaded into the internal register where it is decoded.
