Design Considerations for a Low-Cost Sensor and A/D Interface
Most sensors are inherently analog and must have their signals digitized before they can be used in today’s electronic systems. This application note will cover the basics of ratiometric sensors and how they interact with analog-to-digital converters (ADCs). In particular, it will show how the ratiometric characteristics of sensors and ADCs can be exploited to improve accuracy while simultaneously reducing component count, lowering cost, and reducing board space.
