10 Power Supply Recommendations

The power supply can be any voltage between the minimum and maximum supply voltage rating located in

the Section 6.2. Each VCC terminal should have a bypass capacitor to prevent power disturbance. A 0.1-μF

capacitor is recommended for this device. It is acceptable to parallel multiple bypass caps to reject different

frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor

should be installed as close to the power terminal as possible for best results, as shown in Figure 11-1.
