Maximum no of PGAs in PSoC3

Question: How many PGAs can be placed in Creator in PSoC3.

 

Answer:

 Whenever a PGA is placed in Creator it uses SC/ST block. PSoC3 has 4 inbuilt SC/CT blocks, all of them can be used as PGA. Apart from them, there are 4 naked Op Amps, they can also be configured as PGA but with unity gain. For variable gain you need to connect external resistance on the feedback and input path of the naked OpAmp.
