Values shown are for 200mV full scale, 3 readings/sec., floating
supply voltage (9V battery).
Values shown are for 200mV full scale, 3 readings/sec. IN LO may
be tied to either COMMON for inputs floating with respect to
supplies, or GND for single ended inputs. (See discussion under
Analog COMMON.)
