Description

Boxed ground is the quietest. The magnification is high. In the case of unpacking, it is easy to induce interference to the board and affect the signal-to-noise ratio.

When using ALPS27, it is recommended to use 10K. When using ALPS16, if there is no value of 10K, choose 50K.

Use points:
The power supply is adjusted to ±17V or ±15V, respectively, the 4th pin of the op amp = -17V and the 7th pin = +17V
After adjusting the power supply, you can plug in a single op amp independently, and leave the rest unplugged. Adjust the corresponding adjustable so that the output (the 6th pin of the op amp) is the closest to 0MV
The op amp is recommended to use AD797, or NE5534 LME49710 can be selected
PCB size is 147X96MM
