HA-2400 four-channel programmable amplfiier is used as non-inverting four-state attenuator controlled by logic inputs 0 and 1 to D0 and D1. Output voltage for each logic combination is given in truth table. Values shown provide gains of 1, 1/2, 1/4 and 1/8.-W. G. Jung, IC Op-Amp Cookbook, Howard W.
