For digital systems, conversion of such analog voltage signal to a digital code is also required. MEMS pressure sensors inherently provide a highly linear output that requires amplification and temperature compensation to work in most analog systems. Providing comparative data on two popular MEMS pressure sensors, this two-part white paper will show how pressure sensors with sigma-delta (ΔΣ) analog to digital converters (ADCs) (Part 1) and a sensor evaluation kit (Part 2) simplify design-ins.Īnalog Pressure Output to Digital Input for Control Pressure sensors with a digital output and an evaluation board have two aspects that make design-ins easier. In either case, pressure sensors that are easier to use help designers of products for new or existing applications get their products to market faster. It could be said that there are two types of pressure measurements: those that are made using a MEMS pressure sensor and those that will be. Based on their small size, low cost and high reliability, microelectromechanical systems (MEMS) pressure sensors that use the high-volume manufacturing techniques of the semiconductor industry are found in over 90% of today’s applications. Pressure is one of the most common measurements. Pressure Point 12: Making MEMS Pressure Sensors Easier to Use (Part 1) All Sensors Pressure Points are application tips to simplify designing with microelectromechanical systems (MEMS) pressure sensors and avoiding common pitfalls.
