TSicTM-201 Precise, fast response and Low-cost Temperature Sensor IC Analog 0-1 Volt
Product
Accuracy 0.5 C Measurement range -50 +150 C.. C Analog 0-1 Volt signal output Resolution 0.1 C The temperature sensor family TSic from IST are fully tested and calibrated sensors to allow absolute measurement accuracy at delivery and eliminates further calibration efforts. The temperature measurement with the TSic is very simple, can achieve outstanding accuracy combined with a long term stability.
Advantages
Different accuracy classes with 100% upward compatibility No calibration by customer necessary any more, absolute calibration specified Simple to integrate, reducing cost and time for application-development Robust and elementary signal transmission requires only one singal line Optimum solution for temperature control, thanks to fast data measurement Packages for standard SMD, THT or application specific assembly Miniaturised solutions with Bare-chip (COB, COF, CSP) or e-line package Very fast response time with Bare-chip (COF - Chip on Flex) Very small power consumption - ideal for mobile and standard applications Field (re-)configuration or (re-)calibration available (option for high volume customers only) Outstanding long term stability

Description TSicTM Series
The TSic series of temperature sensor ICs were specifically designed as a high-performance, cost-effective solution for temperature sensing in building automation, automotive, industrial, office automation, white goods and low power / mobile applications. TM The TSic employs high precision bandgap reference with proportional-to-absolute-temperature (PTAT) output; low-power precision ADC; and on-chip DSP core with electrically erasable (EE) memory to precisely calibrate the output temperature signal. TM TSic series of temperature sensor ICs offers devices with two linear analog signal output options such as standard 0~1Vout signal (V+ = 3.0V to 5.5V) or ratiometric (10~90% V+ i.e. 0.5~4.5Vout @ V+=5V) or the digital serial output signal to interface with P controllers.

Accuracy = specification plus quantization error of 1 bit (0.1 This device gets calibrated at 5V. F or C). applications where best accuracy at 3V is requested: ask for a customer specific 3V calibrated device. Accuracy for supply voltage within V+ = 4.5V to 5.5V, 2value. Other TSic products with customer specific calibration available on request: i.e. with special calibration where the 80C span (bandgap) with the high precision temperature range of 0.3 C is shifted to another (lower or higher) temperature range.
