Part Number: MSP430F6779

Tool/software:

Hi Team,

1. With what sampling rate the 24-bit ADCs are working in this MCU?

2. UP tp what harmonic this MCU can calculate accoridngly?

Regards,

Maryam

    Hi,

    The fsd = 2.3MHz max. The OSR is from 1 to 2048. So, the sampling rate would be 2.3M/24bit/1 to 2.3M/24bit/1024, which is from 95.8k to 93.58Hz

    Use 95.8kHz sampling rate for example. 95.8k/10/2 = 4.79k, 4.79k/50Hz = 95th. It can calculate harmonics up to the 95th harmonic of a 50Hz frequency. 

    Best regards,

    Cash Hao
