Hallo,
I have a question.
What are VCTRL0 and VSLOPE in the VCA820 / VCA821 datasheet and Figure7 of the VCA821 datasheet?
The VCA822 / VCA824 have not these specs.
Are these specs for the gain deviation and is UNITS voltage(V)?
Would you please let me know?
Best Regards,
Kazu Ogawa
Hi Kazuhiko,
Yes, the Vctrl0 and Vslope in the VCA820/VCA821 datasheet are constants to estimate gain deviation for different gain control voltages and their units are voltage (V). The below plot in the datasheet with the equation provides the use case for Vctrl0 and Vslope to get an approximate curve for gain vs control voltage plot.
Best Regards,
Rohit
