TEST OBJECT: This is an op amp tester that can be used to test common chips for single op amp(Mono), double op amp and quad op amp. The circuit board can determine whether the IC can be used for amplification, and the conversion rate of the chip can be roughly judged. You can spot low speed chips that in the disguise of as high speed chips
OUTPUT MODE: For high speed op amp, can output normally when input high and low frequency square signal, as the corresponding red LED and green LED synchronization, steady on(200KHZ or bright (10HZ))
OUTPUT DISPLAY: For low speed op amp, when input square signal, the output end can not complete the output waveform, as shown by the corresponding red LED can not be lit normally, only one or two are not lit. Only when the low frequency is input can be output normally, and the corresponding red LED at the output end can flash synchronously with the green LED
TEST CURRENT: A test terminal is provided on the board to test the static current of the op amp under plus or minus 5V power supply. Through the static current size, you can also understand some characteristics of the operating amplifier, and distinguish the model
STABLE PCB: Operational amplifier test board adpot stable PCB material, possess excellent maintainability and interchangeability, rest assured to use
