ADC12DJ5200-SP: Recommended Ripple/PDN Requirements

Joseph Sanchez

Part Number: ADC12DJ5200-SP

Hello, we're hoping to get a spec for the recommended allowable ripple on the 3 power supplies for this part. Even better would be a recommended impedance to shoot for on the PDN.

Thanks,

Hi Joseph,

Please see the following articles in understanding the allowable ripple on the power supply and overall guidance on the PDN design.

Thanks Rob. Yeah we're matching the PDN for the EVAL board so the 1.1V supplies are below 40mΩ and the 1.9V is below 60mΩ.
