Op Amps Without Op Amps - Workbench Wednesdays 39

Okay, technically, this circuit *does* use Op-Amps. However, the ones shown here are integrated into an ATmega128DB microcontroller from Microchip. The DIP package breaks out two operational amplifiers that are controllable entirely by software. Even better, you can program like they are an Arduino!

  • Great demonstrations of the chip features.

     

    At first I wanted to write that it seems like the competition is only slowly trying to catch up with Cypress PSoCs that also feature ADC, voltage / current DAC, op amps / comparators and analog multiplexors and most importantly a graphical IDE (PSoC Creator) that makes the development super easy - you can draw a schematics that is part of the project.

    However, newer PSoC 6 is recommended to be developed on a multiplatform Eclipse-based IDE (Modus Toolbox) that lacks the graphical editor.
