Does analog devices provide sigma delta ADC with on chip switches?(This can be used to replace the switches (ADG1414 and AD442) in cn-0209, right?)
The AD7193 contains a single sigma delta ADC but it includes a mux in front of the ADC so the part can accommodate 4 diff inputs or 8 pseudo-differential inputs. Another option is the AD7194 which can accommodate 8 diff inputs or 16 pseudo-diff inputs.
For now you can check out the ADAS3022/23, there is an internal switch MUX in the front end with SAR ADC on a single chip. As for sigma delta ADC, I will have to get back to you.
There are a number of sigma delta ADCs that contain internal switch MUX in the front end. Including the AD7193 found inside the CN0209. May I ask what specific application you intend to use the switch and ADC with, so that I can recommend an ADC that is more suited to your specific need.
Thanks. We are trying to design an analog input module and we are planning to follow the CN-0209 design.I was asking whether I could replace the switches used in CN-0209(ADG1414,ADG442) and ADC AD7193 with a single ADC .
Thanks and regards,
