SensorDynamics SD400 Sensor Interfaces
The SensorDynamics SD400 is a single chip sensor interface family. The SD400 family features a set of analog blocks for interfacing with a wide range of sensors with various working principles to be used in different challenging and safety relevant applications. SD400 combines the flexibility of free programmable standard interface products with the advantages of an optimized custom specific solution. SD400 and development tool kit are available now. The kit includes an evaluation board, ASM/C code compiler, drivers, basic C code examples, user manual and a programming GUI for easy ASIC configuration. Pricing for the kit is US $750.
SD400 Applications
- Position sensing in automotive applications based on Eddy current or AMR/GMR principle like clutch-, brake-and accelerator-pedals, gear shifters and suspension control.
- Position sensing under harsh environment up to 150 Degree Celsius like in valves, transmission- and transfer-cases based on Eddy current principle.
The SD400 family consists of two versions. First version has a specialized Eddy current interface, designed for contactless displacement measurement. Besides the interface chip, only a sensing coil plus a few passive components are needed for the application circuit. A metal target facing the coil completes the distance measuring system which is best suited to work under harsh environments. Second version provides two differential analog input channels. Wheatstone bridge type sensors as thermocouples, AMR-, GMR-, piezoresistive pressure-, water flow- and strain gauge sensors can be adapted easily to the interface chip as well as single-ended sensors.
