I was looking for a ADC chip set with 16 bit or 24 bit resolution having capture buffer(FIFO) of 1024 samples and a interrupt line once capture buffer is half filled 512 samples the ADC interrupts the processor to read data from capture buffer (so basically capture buffer must work like FIFO) using SPI or any serial interface
data is sampled at the rate of 10 Hz to 1kHz
sigma delta ADC
power consumed must be of the order of 2 mW
each chipset can have single channel input or a multiple channel
if you have a chipset that consumed slightly more power then also please let me know or if you have a chipset with FIFO size lesser then also let me know
but mandatory criteria is FIFO is a must but FIFO length can be of any size i need 1024 but if it is 256 then also its fine
and power consumed must be low of the order of 6 mA
We regret to say that we do not have ADC parts that have an internal FIFO (capture buffer). ADI have never created a device with such a function.
Anyway, can I ask why are you interested to an ADC with an internal FIFO? I'm assuming that you do not want the processor being interrupted by the ADC continuously, is this the case? If so, in what particular application do you intend to use this type of device?
Apology for the delay in replying to your query.
