AD9834 - How to improve the accuracy and temperature stability

Thread Summary

The user asked about improving the accuracy and temperature stability of the AD9834 output amplitude. The support engineer suggested using an external precision voltage reference, such as the ADR3412, connected to the REFOUT pin, and provided a reference document (MT-087) for guidance. The user agreed to try this in a new design.

AD9834 - Is there any way to improve the accuracy and temperature stability of the output amplitude?

The internal voltage reference have an output impedance of 1kOhm, so could it work to connect a precision voltage reference such as ADR3412 to the REFOUT pin?
