KWD 5.500
– 1 +

Special Features

  • 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.

Description

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.

Working Voltage: DC 12V

Working Current: Above 100mA

IC1a in the circuit is connected to a multivibrator with a frequency of about 1Hz, and the OP Amp. to be tested is connected to a unity gain inverting amplifier working state.

IC2 is an EX-OR gate, and its truth table is that the output is 1 when the two inputs are inverted.
