Part Number:REF2030
Hi,
I plan to use 5 ADS7057 ADC simultaneously. I supply the AVDD rails using a REF2030 voltage reference with 20mA source current capability. The REF2030 maximum recommended output capacitor is 10uF. The ADS7057 datasheet recommend a 3.3uF decoupling capacitor on the AVDD rail. Is it fine if I put 1uF close to each ADC plus a 4.7uF on the output of the REF2030? Is there any better configuration? What is the recommended decoupling scheme?
Best regards,
