unipolar output operation
The unipolar output operation is the basic mode of operation for each channel of the TLC7226, with the output
voltages having the same positive polarity as Vref. The TLC7226 can be operated with a single power supply
(VSS = AGND) or with positive/negative power supplies. The voltage at Vref must never be negative with respect
to AGND to prevent parasitic transistor turnon. Connections for the unipolar output operation are shown in
Figure 7. Transfer values are shown in Table 3.
