상품특징
Working voltage: AC5-16V or DC6-24VThe pre-amplifier is designed with two op amps, and one op amp is used for one channel, and the effect is much better than that of a single op amp and two channels.Built-in single power supply to dual power supply chip, so that it has the effect of dual power supply under single power supplyUse large-capacity filter capacitors with rectifier circuit, which can be used for both AC and DCR1, R5 are the magnification setting resistors (the default is about 5 times magnification for delivery, you can change the magnification according to your own needs, the resistance can be selected from 5k-100k, the larger the resistance, the higher the magnification, if you use a plug-in resistor , you can remove the original chip resistor by soldering, and solder the plug-in resistor on the pads at both ends of the patch position)
상품설명
Features: 1. Using high-quality materials, the quality is guaranteed 2. The pre-amplifier is designed with two op amps, and one op amp is used for one channel, and the effect is much better than that of a single op amp and two channels. 3. Built-in single power supply to dual power supply chip, so that it has the effect of dual power supply under single power supply 4. Use large-capacity filter capacitors with rectifier circuit, which can be used for both AC and DC 5. Wide range of applications parameter: Working voltage: AC5-16V or DC6-24V PCB size: 50mm*50mm Overall height of the board: about 23mm R1, R5 are the magnification setting resistors (the default is about 5 times magnification for delivery, you can change the magnification according to your own needs, the resistance can be selected from 5k-100k, the larger the resistance, the higher the magnification, if you use a plug-in resistor , you can remove the original chip resistor by soldering, and solder the plug-in resistor on the pads at both ends of the patch position) Package list: Amplifier board*1 Signal line*2
