URGENT:Number of Operational Amplifiers Available on PSOC 5 - Cypress.com Forums http://www.cypress.com/? Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78159 If you need OpAmps for CT filter work there are solutions for both fixed G

and infinite G topologies. Read you can use a PGA in certain fixed G solutions.

However, you need to do stability analysis, and PSOC characterization not quite

there to do that. So you can do phase margin tests real time (step response) to

establish how much marging you have.

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78153 You might be able to use the PGAs as amplifiers, dependinh on whether they work in your circuit or not.

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78150 Thanks Hli for the info on SCblock. Is there any sample projects that use SCblock?

According to PSoC TRM manual, this block is configured using SC_CR0 register. But the SCblock symbol only shows dyn_cntl input.

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78149 In that case, May be it is better not to let user use it direcly :-(

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78145 This is more a compatibility problem. The public components are (more or less) guaranteed to be compatible between Creator revisions, or even between devices. When switching between PSoC3, 5 and maybe even 4 you don't really need to change your component configuration, only the source code (e.g. when using DMA). But when you start using the internal building blocks, you depend on the internals of the choosen PSoC family (and, I suspect, even on the Creator version).

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78136 Does it mean that using this component is not supported by Cypress?

ie "use at your own risk?"

If not, then I would suggest to un-hidden it and make it just like other components, and give it proper documentations.

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78134 Because the SC/CT component are not intended to be used directly. Only the components using it are (e.g. the PGA or the Mixer).

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78093 To get an idea of familiy resources there are several approaches -

 

1) Download the top level datasheet for each familiy, and examine the summary chip specs at beginning

of data sheet.

 

2) Use product slector in each design tool, Creator, Designer and filter columns.

 

3) Brochure, to a lesser extent, www.cypress.com/?rID=2545

 

4) Keep in mind many designs can "share" resources, because of analog mux capability. Or digital filter

approach for multiple filters. Sample and hold, A/D with mux on front end......

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78088 There are not data sheets for the internal components. You will need to look at their accompanying source code for more information.

Or you import a component using it into your project to look at an usage example:

  • open your project, go to the 'components' tab in the workspace explorer
  • right click at the project, 'import component'
  • look for the component, e.g. from 'CyComponentLibrary' the component 'Mixer_v2_0'

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78082 In Creator, go to "Tools / Options", open "Design Entry / Component Catalog". Check the "Show hidden components" box. Then the internal building blocks appear (you want to get the "scblock", I think)

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=78072 Hi,

I don't see the SC/CT blocks on the Component Catalog page within PSoC Creator 2.2 .

Where can I get the SC/CT blocks to use in my design schematic?

Thanks,

Hoong Fai

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=58754  Hi,

To sum up PSoC5/3 have opamp resources as below. 

4 Opamps:- These are naked opamps. You can be bulld any opamp circuit using external components. If to be used as follower then there is no need of external connection as there is a switch present inside PSoC3/PSoC5 to connect output and negative input terminals. 

4 SC/CT blocks:- These are opamps with bunch of resistors and capacitors around it which can be connected/disconnected to build different opamp circuits. You can configure these blocks as programmable gain amplifiers (inverting and non-inverting), mixer, sample and hold, track and hold, and Transimpedence amplifier (to measure current).

4 Comparators:- These are dedicated comparators with output as digital signal (digital low or digital high). But you can use the comparator to build a shmitt trigger using external resistors. Also, you can build opamp buffer with this comparator by using an external resistor and a capacitor. 

 

Thank you

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=58724 Hi Chetan,

 

PSoC3/5 has 4 dedicated Operational Amplifiers.

You can use external components such as resistors and capacitors to form filters.

There is also SC/CT (Switched Capacitance/ Continuous Time) block which has 4 opamps but with arrays of switches, capacitors and resistors. This block can be used to form an Inverting /non-inverting Programmable Gain Amplifier (PGA), Trans-Impedance amplifier (TIA), Mixers, Sample and Hold, Track and hold, etc.

There are also 4 Comparators available.

Re: URGENT:Number of Operational Amplifiers Available on PSOC 5 http://www.cypress.com/?rID=58723 For PSoC3/5, the biggest one of the family contains 4 op-amps. But there are analog bloacks such as PGAs as well. 

For PSoC1 there are no opamp as such, all ananlog components are using SC bloack.

I think you can have 2 INSAMP or a total of 4 PGA/AMPINV and 4 filters. However, the actual numbers aviable de[pends on  the configuration/arrangment of annalog blocks.
