Hi
I am now facing a problem on my designation using the ADS1281 chip. I have read the datasheet of ADS1281, but there is question to ask and wish you give me a hand.I want to start new convertion per 5ms, that is 200Hz datarate I want, but ADS1281 doesn't surpport the datarate, so I gona to use 250Hz datarate to convert, I mean I start a new convertion and get a sample data 4ms later, then stop convert about 1ms to start a new convertion, this will match my 200Hz datarate, but ADS1281 is a continuously converter, I try to use sync pin to control the convert starting time, but will wait about 64 times datarate periods to start a new convert, that is a long time. so how should I do to achieve this function? Thanks a lot!
