MSB register is the sign bit, Bit 5 through 0 represent the result of bits D[13:8] in two’s
complement conversion. The LSB register holds the conversion bits D[7:0]. The following
equations are used to convert the register values to get the differential voltage:
Figure 6-3 Register of LTC2990
shows the control register of LTC2990. The control register must be configured properly
to measure the voltage difference (V1-V2). Bits b[2:0] should be set to ‘110’ for measuring voltage
difference (V1-V2) and (V3-V4). Bits [4:3] should be set to 00 for all measurements.
