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