  • DAC7811: Output 200kHz Sine signal

    Part Number: DAC7811 Tool/software: Hi tI experts, My customer want to use DAC to output a 200kHz Sine signal, amplitude is 5V. They also need 12bit resolution. Is DAC7811 suitable for this case? Do you have any other recommandation? By the way, what…

  • DAC7811: The application question about Iout2 Pin

    TI Thinks Resolved
    Part Number: DAC7811 Tool/software: Hi team, It's mentioned in ds that the Iout2 Pin usually connected to GND of system. Why in the application section, it's connected to the output of the OPA? Thanks! BRs, Rannie
