Bharath M R Posted May 18, 2023 Share Posted May 18, 2023 Hello everyone, I am new to FPGA, I have some doubts. Can I get the analog output from Nexys 4 board? Link to comment Share on other sites More sharing options...
0 artvvb Posted May 19, 2023 Share Posted May 19, 2023 The Nexys 4 doesn't have dedicated built-in DAC components. You could get an additional module like a Pmod DA4 or R2R that produces analog output and connects to a Pmod header, or you could create your own, using something like a resistor ladder DAC. Depending on your project, one of the VGA color output pins could be used as a 4-bit 0-3.3V DAC, though taking care with output impedance would be important.

0 robfinch Posted June 18, 2023 Share Posted June 18, 2023 You could also use a delta-sigma DAC with an output pin connected to a Resistor-Capacitor. It requires a high-impedance buffer to use the output. Link to comment Share on other sites More sharing options...
