Operational Amplifier Tester Operational Amplifier Tester Module for Single Mono Dual Quad Operational Amplifier Chip High Speed Low Speed Differentiation Module Board
- 1. This operational amplifier test board can be used to test common single operational amplifier, dual operational amplifier, and quad operational amplifier chips, and distinguish between high-speed and low-speed finished boards.
- 2. This circuit board can determine whether IC can be used for amplification and also determine the conversion rate of the chip.
- 3.Equipped with LED indicator light, for high-speed operational amplifiers, they can output normally when inputting high and low frequency square wave signals, manifested as the corresponding red LED synchronized with the green LED, constantly on (200KHZ) or flashing (10Hz).
- 4.There are test terminals left on the board that can test the static current of the operational amplifier under positive and negative 5V power supply conditions. By measuring the static current, some characteristics of the operational amplifier can also be understood, and model differentiation can be made.
- 5.Supported models: Single operational amplifier models: LM741, LF356, NE5534, TL071, TL081, OP07 and other standard packaged single operational amplifiers. Dual operational amplifier models: LM358, NE5532, TL072, TL082, MC1458, RC4558, 0P275, AD827 and other standard packaged dual operational amplifiers. Four operational amplifier models: LM324, TL074, TL084, LF347, AD713, etc

The signal source generates high-frequency square waves with a frequency of 200KHZ and low-frequency square waves with a frequency of around 10Hz, and the tested operational amplifier is connected to a buffer circuit.
For high-speed operational amplifiers, they can output normally when inputting high and low frequency square wave signals, manifested as the corresponding red LED synchronized with the green LED, constantly on (200KHZ) or flashing (10Hz).
For low-speed operational amplifiers, when a high-frequency square wave signal is input, the output terminal cannot fully output the waveform, resulting in the corresponding red LED not being able to light up properly, only lighting up one or both without lighting up. It can only output normally when a low-frequency signal is input, and the corresponding red LED on the output end can flash synchronously with the green LED.
There are test terminals left on the board that can test the static current of the operational amplifier under positive and negative 5V power supply conditions. By measuring the static current, one can also understand some characteristics of operational amplifiers and distinguish between different models.
