Alternatively, program the Input Common-Mode Control
register (04h, see Tables 17 and 18 for configuration
details) through the SPI interface to supply the input
DC common-mode voltage and current through inter-
nal 2kI resistors (Figure 2). When the input current is
supplied through the internal resistors, the input common-
mode potential is reduced by the voltage drop across the
resistors. The common-mode input reference voltage can
be adjusted through programmable register settings from
1.020V to 1.160V in 0.020V increments. The default setting
is 1.100V. CMOUT can be used to provide a common-
mode output reference to a DC-coupled driving circuit.
Reference Configurations
A trimmed internal bandgap voltage generator provides
an internal reference voltage of 1.25V. The bandgap volt-
age is buffered and applied to REFIO through a 10kI
resistor. The buffered bandgap voltage is applied to a
scaling and level-shift circuit, which creates the internal
reference potentials (REFH, REFL) that establish the
full-scale range of the ADC. A simplified schematic of
the reference circuit is shown in Figure 3. Alternatively,
REFIO can be driven externally for greater gain
accuracy, or to establish a different full-scale range.
