Simultaneous sampling of two channels using sample and hold
What is the simplest implementation to sample two analog channels simultaneously using the Delta-Sigma ADC? I was thinking of using two sample and hold components with the output connected to a two channel mux, which is connected to the Delta-Sigma ADC.
The aim is to collect a number of instantaneous samples and then save them to an sd card. I have seen a counter used to identify when a negative edge occurs. I also thought I might be able to supply a negative edge using logic high/low to the sclk pin but it was having none of that.
Is a counter the easiest implementation (using an interrupt to initiate sampling)?
