Does anyone know a solid state way to switch analog inputs sources? ie, switching between different sensors using only one analog input on a chip. I figure it can be done with a relay, but I'm looking for something smaller and in solid state. Does someone know of a chip that might be able to do it. Optimally, it'd be awsome if someone might have heard of something for example like a 16 pin chip with like 8 inputs, 1 output, 3 pins dedicated to input selection and perhaps a power and ground pin.
On that topic, does anyone know of something that can change resistances in solid state with a digital signal? Like a potentiometer only changed with a digital input rather than turning a knob.
The end going is that I'm looking to connect a bunch of strain gauges to a few inputs.
