three-way adder

Overview

This three-way adder uses OPA177 as the operational amplifier, and is designed as a standard three-way in-phase and inverting adder. Short soldering SB2, SB1, and SB3 can be used to switch between in-phase and in-phase. At the same time, the amplification factor can be adjusted by adjusting RP1.
