AD5941 can output sine wave, the min vpp can set low to 10mV or not?
If can set to 10mV, how to set the register?
As per the datasheet, page 43, the DAC that generates the sine waveform is 12-bit.
The equation that governs the output sine wave is:
This give a LSB of less than 1mVpp, meaning 10mVpp is doable.
To do that in the codes, as an example, you can search for DacVoltPP parameter in "AD5940_BIA" example:
Or if you are using your custom code, you can program the registers, whose names mentioned in the datasheet.
Hope this helps!
