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…

Microchip hones dsPIC for digital-in-the-loop power

Microchip has announced the third generation of its dsPIC33EP ‘GS’ range, which are DSP-enabled microcontrollers. GS denoted devices specifically intended for fast digital power supplies, which need faster peripherals than, say, motor control microprocessors.

Compared with generation two, they have a faster processor, faster contexts switching, faster higher resolution…
