In Figure 5, VOUT is equal to VBIAS when the sum of all
outputs is zero. For positive input-sense voltages, the
MAX9934 sources current causing its output voltage to
rise above VBIAS. For negative input-sense voltages,
the MAX9934 sinks current causing its output voltage to
be lower than VBIAS, thus allowing bidirectional current
sensing.
Since the ADC reference voltage, VREF, determines the
full-scale reading, a common choice for VBIAS is
VREF/2. The current output makes it possible to use a
simple resistor-divider from VREF to GND to generate
VBIAS. The output resistance for gain calculation is the
parallel combination of the two resistors. For example, if
two equal value resistors, R, are used to generate a
VBIAS = VREF/2, the output termination resistance for
gain calculation is ROUT = R/2. See Figure 5.
