Figure 5−1. External Component Connections
Figure 5−1 does not show the decoupling capacitors for the power supplies. Texas Instruments recommends
using at least one 0.1 μF capacitor for each power supply pin. In addition to the 0.1 μF capacitor, Texas
Instruments recommends adding 0.01 μF and 0.001 μF capacitors for each analog power supply pin. Texas
Instruments also recommends isolating the analog power from the digital power.
