Design ideas: Some practical ways to split a voltage rail

There are a number of reasons why an engineer would want to “split” a voltage rail in their design. Sometimes parts of the circuit, like a sensor or an IC, require a bipolar supply.

Other reasons are to make the best use of the dynamic range of your ADC if…
