analog mux

[SeanHodgins] has a project in mind where he needs to sample over 500 analog sensors. To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the ...

Use an analog multiplexer to measure current from multiple input channels

There are different methods to measure current. One method is to use a resistor across a current output and measure the voltage. The voltage across the resistor is measured using ohm's law: where I is ...

Double The Resolution, From An Arduino ADC

Analog-to-digital converters, or ADCs, are somewhat monolithic devices for most users, a black box that you ask nicely for the value on its input, and receive a number in return. For most readers, ...

Multiplexing a 1-Wire host across multiple channels

*The AB_ and COM_ pins provide +10 kV ESD protection (HBM). Any 16 AB_ pins can be connected to either COM_ pins. All of the recommended analog muxes handle rail-to-rail analog signals, have a small R ...

Universal analog-to-digital multiplexer-demultiplexer

As is known, a multiplexer and a demultiplexer is an electronic device designed for selective signal transmission from one of several inputs to one output, or, on the contrary, signal transmission ...

32-Channel PCI ADC Board Overcomes Speed Limitations

The 32-channel PCI-417N series parallel-sampling PCI analog-to-digital converter (ADC) board streams at 14-bit resolution. A 32-bit wide on-board DMA PCI bus master offloads the host CPU. To avoid the ...

Take The PGA Tour Through Analog-Digital Interfacing

Lying at designers' fingertips is an ever-widening range of programmable-gain amplifiers (PGAs) to handle the interface between real-world analog outputs of sensors/transducers in data-acquisition ...
