The ADS8320 is designed to operate using a simple power supply voltage from 2.0 V to 5.25 V, but the specifications are ensured over a 2.7-V to 5.25-V supply range. This supply must be well regulated and bypassed. A ceramic decoupling capacitor must be placed on the supply pin as close as possible to the ADS8320 package. In addition, a 1-µF to 10-µF capacitor and a 5-Ω or 10-Ω series resistor may be used to low-pass filter a noisy supply.
