10 Power-Supply Recommendations

The devices are designed to operate from an analog supply voltage (V(+VA)) range between 2.7 V and 5.25 V and a digital supply voltage (V(+VBD)) range between 1.7 V and 5.25 V. Both supplies must be well regulated. The analog supply is always greater than or equal to the digital supply. A 1-µF ceramic decoupling capacitor is required at each supply pin and must be placed as close as possible to the device.
