i'm trying to use ad7616 for new design which is having more than 80 channels on 2FMC's and i need to design for synchronized data... can anyone tell me how to use this IC for synchronization purpose without any clk or sync pin's.
and how to conform that data is processing at what speed without ref clk in parallel communication.
how much timing relaxations can be taken in ad7616-p than ad7616
its little bit urgent ...any one can u plz help me to get knowledge about this to finish this design...
thank you in advance
The AD7616 has no synchronization pin to preform a synchronize multiple device. The closest way I can suggest is having a common reset for the multiple device. Once a reset is release, the device are fully functional and a conversion can be initiated. By the way what application are planning to work on? I asked this because there other ADCs available in ADI portfolio that has sync function like AD7768 which is also a multiple channel ADC.
This is multi channel ADC like 40 channels should be connected to FMC . For this i need min 1msps speed with 16bit digital output. for this requirement i didnt get any other IC . can you plz help me to get find solution for this requirement.
can you please suggest me any IC to meet my requirements... 40channels of adc with 16bitdata, min 250ksps speed and need synchronization on 3 IC's(if consider AD7616)
The AD7768 is a 24bit 256ksps 8 channel sigma delta ADC. I think this can fit your application. Do you have a bandwidth requirement for your application? You can check the datasheet of the AD7768 here.
The AD7616 can also be use by connecting in parallel and using the same SPI and having common CONVST signal.
