is is also possibleto configure the DAC1-3 of the ADC7343 to RL=75Ohm?
The Datasheet only mentions 300Ohm and 37,5Ohm. I would assume 1020Ohm for R_set.
In theory, yes you can change the load resistor however ADI has only characterized the device for 37.5 and 300 Ohm loads as shown in the data sheet implementations. The ADV7343 is a DAC output with RSET setting max output current. So you can change loads but you will have to certify that it meets your requirements with a different loads .
