Hello.

I have a question.

How should I calculate the value of Tsample in the ADC10 ?

I am using MSP430F67471A.

The method to calculate Tsample value using capacitance and resistance in ADC12 is described in user guide.

But that in ADC10 is not described only writing sample value of Tsample in the data sheet.

When I estimate Tsample value in the ADC10, can I use method to calculate Tsample value

-in the ADC12 described user guide page 737 ?

Hello Uchida-k,

Please use the Tsample equations from page 737 of the User's Guide along with the CI and RI values in Table 5-47 of the device datasheet, minimum Tsample timing parameters are provided in Table 5-48 for your convenience. The sample-and-hold time is set by the ADC10SHTx bits of the ADC10CTL0 register.

Regards,
Ryan
