ADC12DJ5200RF: Foreground calibration time

Mathieu Kraus
Prodigy 50 points
Part Number: ADC12DJ5200RF


In datasheet, we see : "user must wait a sufficient time before programming the device to nake sure the calibration is finished"

What do you mean by sufficient ? 10ms ? 100ms ? 1s ?

On what depend the calibration time ? 

Could the foreground calibration be done in factory and stored in memory ?

    Hi Mathieu,

    The foreground calibration time is dependent on ADC sampling clock. With ADC running at 5.2GHz clock it will take around 180msec to perform foreground calibration. 

    The foreground calibration is performed at the device startup and anytime after that if  the temperature of ADC changes by more than ~20C from point when the last foreground calibration was performed.
