    Thread Summary
    
                The user asked about the DC bias voltage for the sine wave produced by the IOUT and IOUTB channels of the AD9834 when connected to a 200-ohm load resistor. The final answer provided by the support engineer is that the DC value is around 320 mV. The support engineer also recommended the LTSpice model of the AD9834 and the user guide for further details on using an instrumentation amplifier with the device.

    The IOUT and IOUTB of the AD9834 output to a 200-ohm load resistor. What is the DC bias voltage for the sine wave produced by each channel? I want to connect an instrumentation amplifier afterwards, as my sine wave signal frequency is relatively low.
    

    Thank you.
