Generation of constant current - ADuCM350

Hello,

I am not sure but I would like to know if it is possible to generate a constant current with the ADuCM350 chip or if it is a voltage generation module inside that is doing the job ?

Thanks in advance.

    Hi,

    DC voltage can be generated by assigning DAC code to DAC (Figure 43 of ADuCM350 datasheet).

    Tis include:

    1) Disabling excitation amplifier in AFE_CFG,

    2) Enabling DAC and Waveform generator in AFE_CFG,

    3) TYP_SEL = 0X in  AFE_WG_CFG register.

    Giving the desired value to  AFE_WG_DAC_CODE register.
