Product Description

instructions: 1. Connect a 12VDC power supply to the circuit board, and at this time, the three red LEDs on the board will light up. 2. Insert the operational amplifier to be tested, paying attention to the direction of the notch. The left socket is for testing order operation, with two red and yellow LED indicators on the top. The right socket is for testing dual operational amplifiers. The upper two sets of red and yellow LEDs correspond to the two chips inside the dual operational amplifier. 3. After inserting the chip: If the operational amplifier chip is functioning properly, the yellow LED will light up and the red LED will turn off; If the output of the operational amplifier chip is open circuit, the yellow LED will turn off and the red LED will light up. If there is a short circuit inside the operational amplifier chip, the red and yellow LEDs will flash alternately. For chips with low conversion rates, the LED indicates a constant yellow light and a slight red flicker. This can also be used to roughly determine the high or low conversion rate of the chip. Because most of the motorcycle chips sold on the market use low conversion rates instead of high-speed ones Actual testing of low conversion rates, such as: OP07，LM741， Yellow is always bright, red is slightly bright. Test high conversion rate chips such as TL071, NE5534, MC34071, etc., with yellow constantly on and red not on. Single transport model: LM741, LF356, NE5534, TL071, TL081, OP07 and other standard packages for single operation and placement. Dual operational amplifier models: LM358, NE5532, TL072, TL082, MC1458, RC4558, OP275, AD827 and other standard packaged dual operational amplifiers. PCB size: 9.2×5.8 cm Power supply requirements: Voltage: 12VDC, current above 100mA.

• Single op amp and dual op amp screening circuit board, the circuit board can judge whether the IC can be used for amplification, and can roughly judge the conversion rate of the chip at the same time. Can find out those low-speed chips that pretend to be high-speed chips.
