Fresh PCBs from factory…. back in stock! OpAmp Test Jig PCB. http://fivefishaudio.com/diy/opamptestjig/
The board can be configured for either Unity Buffer or Amplifier configuration. For the Amplifier configuration, it can be selected for either Non-Inverting or Inverting configuration. Gain is adjustable via jumpers from 0dB to 72dB Maximum. Loading of the OpAmp can be set via a switch, for eitehr 600-ohms or 10Kohms (or whatever resistor value you want). On-board BNC jacks allows easy connection to a signal generator and oscilloscope or some other test equipment like a Distortion/Signal Analyzer.
You can use this OpAmp Test Jig to test either PDIP, or discrete Op Amp like our DOA-12 or DOA-17 OpAmps.
I ordered one of these, but I have one question (beware n00b)… I don’t understand the markings for the LEDs. I can’t figure out the polarity of the two LEDs. Can you help this beginner please?
Steven, depends on whether you purchase common anode or common cathode LEDs. Best foolproof way is power up the board, insert led into hole and take note of which direction it lights up. The 2 LEDs for v+ and v- will be opposite polarity
