15 thoughts on “ Arduino Analog I/O Multiplexer ” frankbuss says: June 9, ... Of course, with 500 input and multiple of these chips, the CS signals etc. make sense, ...

But cosimulation — simulating both analog circuits and a running processor — is often only found in high-end simulation products. ... the output from the Arduino is the input to the circuit).

First, let’s consider the operation of a control node containing key elements controlled by digital input signals. Figure 1 shows an example of such a node based on discrete elements such as bipolar ...

When you expand the circuit for more inputs (for example, using the four-input multiplexer in Figure 2a), you must take the extra sampling time into account. To maintain a low duty cycle and thus ...
