ZMD America and IST Debut TSic Temperature Sensor ICs

ZMD America (Melville, NY), a wholly owned subsidiary of ZMD AG (Dresden, Germany), and Innovative Sensor Technology IST AG (Wattwil, Switzerland), a sensor manufacturer, announced a breakthrough in high-precision temperature sensor integrated circuits (Tsic) as a result of their collaborative product development. The two companies introduced the TSic™ family of temperature sensors with accuracy levels of ±0.5°C, ±0.3 °C, and ±0.1 °C.

Critical issues for achieving the specifications were the selection of the appropriate semiconductor technology, analog design, and the robustness and simplicity to read high functionality of the digital signal transducer, and ZACwire™ data transfer. The digital sequential data transfer offers a solution with minimal development effort. The TSic sensor family features low-power consumption of 45 µA and a supply voltage of 2.973.0 V to 5.5 V. The sensors have a self-heating temperature of less than 0.07 °C, making them suitable for mobile devices, high-precision measurement systems, products requiring fast temperature control, and applications requiring wireless digital signal transmission.

At a size of 1.6 mm x 1.5 mm, the sensors are available now in two packages. The SOP-8 (SOIC-8) and in e-line (TO-92 compliant) packages.
