APPLICATIONS
Any circuit function which can be constructed using a conventional operational amplifier can also be constructed using any channel of the HA-2400. Similar or different networks can be wired from the output to each channel input pair. The device can therefore be used to select and condition different input signals, or to select between different op amp functions to be performed on a single input signal. To wire a particular op amp function to a channel, simply connect the appropriate network between the two inputs for that channel and the common output in the same manner as in wiring a conventional op amp. It is often possible to design with fewer external components than would be required in wiring four separate op amps (see Application Numbers 2 and 3 on the following pages). It should be remembered that the networks for unselected channels may still constitute a load at the amplifier output and the signal input, as if the unselected input terminals were disconnected from the network.
