AD828 Op-Amp Preamplifier Module Amplified Board Module Op-Amp Preamp Board Amplifier with Imported Capacitors and Gain for Pro

The input and output coupling capacitors use imported non‑ capacitors, with stable performance The op amp uses fever‑grade AD828 patch, fine production process and professional design Full chip production process, small size design, can change the magnification by yourself Item Type: Amplified Board Module Material: Plastic Model: AD828 Working Voltage: 5-15V Magnification Adjustment: R7, R5 are the magnification setting resistors (the default delivery is about 5 times magnification, you can change the magnification according to your own needs, the resistance can be selected from 5k-47k, the greater the resistance, the higher the magnification, if you use plug-in resistors , You can remove the original chip resistor, and solder the plug-in resistor on the pads reserved at both ends of the chip position
