Im trying to use a AD7524 to go from 0 V to Vref (5Volts). Is there any schematics, except the datasheet that can show me how this can be done?
I want 1111 1111 to represent aproox 5 V and 0000 0000 to be 0 V. In other words, i want the analog output to be Vref, not -Vref.
There is an alternative circuit, the voltage switching mode, not using negative voltages. Although it is an existing option, we cannot garantee a good performance of the part as there is no characterization data for this configuration.
VIN is connected to the Iout1 pin, which needs to be a voltage between 0.3V and 1.4V to maintain decent linearity.
Please refer to the AD5424 datasheet for more detailed information. http://www.analog.com/static/imported-files/data_sheets/AD5424_5433_5445.pdf
