ADS1178 at 2KHz

Luiz Paulo Rosa Abrantes

Other Parts Discussed in Thread: ADS1178

My question is, how can I use the ADS1178 to sample every 2 KHz (500 us). Is it possible? You must always use SYNC signal to generate an event?

Thanks

Hi Luiz,

The SYNC pin requires some additional time to clear out the digital filter and start conversions so I would not use that method to achieve a 2KHz sample period. The best way to do it is to adjust the master clock since the data rate will scale with the master clock. So, depending on the mode you place the converter in, you can adjust the master clock accordingly to get the data rate you are looking for.
