Do the end to end cost analysis, cost of engineering time,
board area, reliability, connections, reference, analog precision
needed........some conclusion will be PSOC, some not.
Agree, on chip opamps not state of the art. But in OpAmp shipments
stuff like LM324 like grunge parts still the principle volume in industry.
And auto zero type techniques, correlated double sampling techniques,
mitigate some of that. Small FPGA, for sure its small. Look at the number
of threads on this forum where designers want small FPGA, small amounts
of logic to add to designs. Reason for success of single gate logic families.
PSOC is not for all designs, just many.
No one is claiming PSOC is the god of solutions. But sound engineering
has shown it has its place.
Every single thread with a micro controller, they de-rail, with "oh do this with a PSOC".
That is a BS statement.
