Hello TI Community :D
Brief explanation of what I am trying to achieve: I am building an analog extension to an existing digital system. It is supposed to receive two digital signals from this system as input and feed back another two signals as output (so I need 2 DA converters for the inputs and two AD converters for the outputs) On the analog side, the converted signals are used to drive a sensor and perform measurements.
I am looking for AD/DA converters that meet the following requirements:
- synchronization of all 4 converters possible through external triggering
- resolution of 24 bits (at least for the ADs)
- at least 1MSPS for the ADs (preferably 4MSPS)
- DAs with a settling time that matches the above sampling rate
- same type of interface for the AD/DA pairs, preferably parallel
So far my search has yielded the following ADS1675 + DAC8831, but I would like to ask if anyone has better suggestions. I would really like to avoid using a serial interface (the digital system is FPGA based and allows complete freedom with respect to interfacing). Devices with DIP variants would help as I could build a prototype by hand on a raster PCB before ordering one from a Fab house.
Many thanks
