OP_AMP_TESTER

The circuit is a simple dead or alive test for an op amp. It is an oscillator that produces a 1500-Hz square wave, audible as a tone in the speaker. By looking at the output with an oscilloscope, you can measure the rise time. Several op amps can be tested at once by cascading them, as shown in the diagram.
