Melville, New York ZMD America and Innovative Sensor Technology (IST) AG claimed a breakthrough in high-precision temperature sensor ICs with their highly accurate TSic family.
"By utilizing IST's capabilities to calibrate high-precision sensors, these devices offer companies an accuracy rating that we believe is a factor of five above devices currently in the market today," said Thilo von Selchow, ZMD's CEO.
There are five new products available: TSic 106 (±0.5°C accuracy at room temperature), TSic 206 (±0.5°C accuracy from +10°C to 90°C), TSic 306 (±0.3°C accuracy from +10°C to 90°C), the TSic 506F (±0.1°C accuracy from +5°C to 45°C, and -0.1, +0.2°C) and the TSic 706VHA (±0.05°C accuracy from +35°C up to 45°C).
Critical issues for achieving these breakthrough specifications were the selection of the appropriate semiconductor technology, analog design, the robustness and simplicity to read the digital signal transducer, and ZACwire data transfer, von Selchow said. "The digital sequential data transfer offers a compelling solution with minimal development effort," he added.
The TSic sensor family features low-power consumption of 45μA and a supply voltage of 2.97 V to 5.5 V. The sensors have a self-heating temperature of less than 0.07°C for mobile devices, high-precision conventional measurement systems, products requiring fast temperature control, and applications requiring wireless digital signal transmission.
The sensors are available now in SOP-8 (SOIC-8) and an e-line (TO-92-compliant) packages. Measuring 1.6mm x 1.5mm, the calibrated sensores are practical for chip-on-board, chip-on-flex, and chip-scale packages. Other customer-specific packaging, output configurations or temperature calibration ranges are available for high-volume applications as well.

Pricing depends on accuracy and starts at $1.14 for the SOP-8 style (±1°C) and $2.28 for the SOP-8 (±0.3°C) in 500-piece quantities.
