I want to know the maximum output voltage and current levels of DAC AD9122. How much output voltage we can generate? and How much maximum output current generate?
The AD9122 is a current output DAC which is programmable via the SPI registers as to what the full-scale current setting is set to. The voltage swing will depend on the output current settings chosen as well as the termination resistors at the output. The evaluation board has 50 ohm termination resistors. If you use the default full-scale current setting in the part of 20mA and do not change this, the swing will be 1V (20mA * 50 ohms). Please check the datasheet for more information, reference the "Analog Outputs" section which goes into more detail about the current outputs of the DAC.
Please anyone tell me the maximum output voltage given by ad9122 evaluation boards. I have read the datasheet and ad9122 evaluation boards example but no where is mention the maximum output voltage given by ad9122 evaluation boards.
Thanks and Regards
I got the answer in application note of ad9122:CN-0205
