DAC37J84EVM: How to controll the DC offsets of waveforms.

Part Number: DAC37J84EVM
Other Parts Discussed in Thread: DAC37J84

Hello,I want to generate arbitrary waveforms including DC offset control with DAC37J84 & TSW14J56EVM setup.However, I couldn't control the DC offset (probably a high pass filter inserted?).

Is there a programmatic solution to this problem?

Best regards

  • Hi,

    The DC offset programming will need to be initialized again after register programming. This will prevent glitches occurring to the DC offset when writing multiple registers of DC offset programming. You may do so by writing a simple SIF SYNC register to DC offset block:
