Hi All,

 

We are using AD7292 in our design but we are facing some problem in implementing the alert function(pin nos. 26 and 27). we have a query regarding the same:

 

For ADC conversion , do we need spi clock (SCK) every time for new conversion?

 

We have issued conversion command 0x1 0x8e and kept the chip select low. However no clock is provided after chip select is kept low, until we write something in Dout. As a result we do not get the alert pin toggle. Is spi clk necessary for ever conversion to take place?
