MSPM0G1507: Settiling error in ADC

DDdoor

Part Number: MSPM0G1507

Hello,

I try to suppose to calculate Min sampling time based on equations in 7.12.4 Typical Connection Diagram in the data sheet of MSPM0G1507 but Settling error is not defined.
What is Settling error?

Best regards,
DDdoor

Hi DDdoor,

The settling error is in LSB. In general, most use cases have the error to 1 LSB.

The ADC is a SAR ADC and will behave like a typical single-ended SAR ADC. I recommend looking at our TI Precision Labs for ADCs to help cater the timing to your system.
