Part Number:DAC8760
Hello.
I am planning to use the DAC8760 in a new design for industrial analogue output, that can be configured for either 10 V or 20 mA output. Here the DAC8760 seems to fit perfectly.
I have to put some filters in the output. These filters gives an ohmic resistance for 50R and 20R as shown in the schematic drawing below.
In voltage output mode the 20R resistance will give 0,2% failure when the output is 10V with a 1 Kohm load, so I was planning to use the -VSENSE input to compensate for this error.
My question is if it is the correct way to use the -VSENSE pin. The datasheet says that the voltage level on this pin should only be a few µV from the GND, but in this case it will be up to 200mV. Is this to high? On all reference design I can find, the -VSENSE pin is connected to GND.
Best regards
