With a flexible sensor front end and a wide range of output interfaces, the ZSSC3240 can be used for almost all types of resistive and absolute voltage sensor elements, enabling customers to develop complete sensing platforms from a single SSC device. This combination, along with its small size, makes the ZSSC3240 ideal for use with a wide variety of sensor-based devices for industrial, consumer, and medical markets, including industrial pressure transmitters, HVAC sensors, scales, factory automation devices, smart meters, and continuous smart health monitors.
Micro-machined, silicon-based sensing elements provide very small, nonlinear signals, requiring specialized technologies to convert the sensor signal into a linear output. The ZSSC3240 SSC simplifies both the design and production of sensor interfaces by providing highly accurate, programmable, wide-range quantization and gain functions, combined with powerful high-order digital linearization and correction algorithms. The high performance and flexible configuration of the sensor's front end and analog output options enable straightforward sensor platform design using a single integrated circuit (IC). This allows customers to cost-effectively leverage the SSC for a wide variety of sensing elements with differing characteristics.
