Published Date: 09/06/2011

Description

As new generations of microcontrollers lower 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 analog-to-digital converters (ADC) are discussed.
