The first is the adjustable potentiometer, res beginning, seems to be res - pow, the second and the third is the op-amp, find opa or a beginning in the beginning, these components encapsulation and schematic diagram can be drawn themselves,CodePudding user response:
1) potentiometer, (2) operational, this is the general principle diagram,Name brands, different models and parameters is not the same, need to choose according to your actual device can decide encapsulation,
Instrumentation, SMT has, SMT also according to the parameters, such as power factor has different forms, see you are using AD, instrumentation in the tool, SMT packaging wizard, basic are commonly used packaging, can point in your look, will be a little bit more intuitive,
