Part Number: DAC5687EVM
Hi,
I want to use my dac5687evm board in unbuffered differential output mode. To monitor the output signal on the oscilloscope, I removed R6, R8, R21 and T2 and install R19 (24.9 ohm) and R20 (24.9 ohm). I make R27, R30 and R32 short circuit. (I just use the B port). When I did not apply any data to the dac5687evm I see 3V dc on J19. When I apply the digital data, I see the analog signal with 0,4Vpp and 2,96Vmean. I want my signal to have 5 Vpp and 0 Vmean. Do I need and op amp circuitry or I can achieve this by some configurations on the EVM?
Thanks a lot.
