In this circuit, the MAX181 internal MUX forms a programmable-gain amplifier (PGA) with digitally-selected gains of 1, 2, 4, 8, 16, 32, 64, and 128. An external fault-protected MUX, the MAX378, selects from 8 input channels and protects the input for up to ±60-V voltage levels. Maxim, 1992, Appications and Product Highlights, p. 8-9.
