If trying to do an up mixer yes -
For the down mixer possibly with internal OpAmp and mux/switches
Possibly port the component to PSOC 4 from 3, 5LP.
You might file a CASE on this, I see as principal limiting problem PSOC 4 routability not
as flexible as 3, 5LP.
To create a technical or issue case at Cypress -
“Create a Case”
You have to be registered on Cypress web site first.
Thank you so much for your valuable answer.
One more thing, How should i gave Vdda/2 voltage? is it externally?
Also i want to program my PGA for all its range. The idea is to increase gain so that the output reaches 1 V, if the input value is less than 1 V. How can i do this automatically?
I am also attaching my project file.
Looking forward for your reply.
Look in datasheet, API section, there is a f() call to set the G
of the PGA, PGA_SetGain(uint8 gain)
Vref is a component you can place on schematic.
Vdd / 2 is one of the setting that can be used for the Vref -
Thank you so much for these quick suggestions. It means alot 🙂
I will look into it.
Thankyou once again.
One thing about Vref, it is, relatively speaking, a HiZ source, so
normally one buffers it with an OpAmp follower.
The Vref is buffered by 5 uA buffers -
