Keywords:interfacing  noise  ADC 

As new generations of microcontrollers cut their supply voltages from 5 V to 3.3 V and beyond, issues with interfacing and noise are increasing. This application report presents cost-effective interfacing techniques for inputs and outputs of 3.3 V microprocessors in an automotive environment. In addition, concerns about 3.3 V analogue-to-digital converters (ADC) are discussed.
