About this item

• Product Introduction AD828 Operational Amplifier Front Amplifier, Audio Amplifier Module, Single Power Supply. Small volume design, full patch process, input and output coupling capacitors using imported non-polar brand capacitors, operational amplifiers using fever grade AD828 patches. Product Parameters Product Name: AD828 op amp front amplifier Product model: 005231 Chip model: AD828 Audio input: onboard interface Working voltage: 5V-15V Product size: 33mm* 25mm Instructions Magnification adjustment: R7 and R5 are the magnification setting resistance (the default magnification is about 5 times for delivery, and the magnification can be changed according to your own needs. The resistance can be selected from 5k-47k. The greater the resistance, the higher the magnification. If the plug-in resistance is used, the original patch resistance can be removed and the plug-in resistance can be welded on the reserved pads at both ends of the patch position)
