The largest family of PSoC3 will give you all of these
1) 4 OpAmps which can be configured as naked OpAmps or as buffers. These are bout 3MHz BW and 25mA drive
2) 4 comparators (Has different modes that vary from low power end to high speed end). But understand these are comparators with outputs going into the digital side of the device
3) 4 SC/Ct block. These kind of like configurable analog blocks with an OpAmp. The drive strengths of these OpAmps are much reduced compared to the OpAmps in (1)
Besides you will also have SIOs which are special IOs with capability to be used as comparators if you run out of the conventional ones..
You mentioned you have multiple signals you are sensing. You might also want to consider multiplexing the analog signals using the Analog muxes avaialable. For example you can multiplex 8 analog signals onto a single comparator but you will incur a response time reduction by 1/8th.
Thank's for your fast answer.
Summerizing, I could use:
- 4 OpAmps.
- 4 Comparators.
- 4 SC/CT Blocks, being possible to use 4 as a PGA, for instantce?
- 8 Comparators with special IO pins funcionality, as far as I know.
Am I right?
