Figure 21. Selection Guide Based on Example Design Requirements
NOTE
Decoupling capacitors are not shown to keep the illustration simple. Decoupling capacitors
(1 µF and 0.1 µF) must be placed close to each power supply pin.
Based on the selection graph shown above, the TCA9802 is selected, since it is the lowest-power device's trace
(grey trace) which touches the shaded region. The TCA9803 may also be used without any consequences.
