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
