from IST are fully tested and calibrated sensors to allow absolute
The temperature sensor family TSic
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 TSic
TM
Series
The TSic
series of temperature sensor ICs
were specifically designed as a high-perform-
ance, cost-effective solution for temperature
sensing in building automation, automotive, in-
dustrial, office automation, white goods and low
power / mobile applications.
TM
The TSic employs high precision bandgap ref-
erence with proportional-to-absolute-tempera-
ture (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 op-
tions such as standard 0~1V
out
signal (V+ = 3.0V
to 5.5V) or ratiometric (10~90% V+ i.e.
0.5~4.5V
out
@ V+=5V) or the digital serial output
signal to interface with
µP
controllers.
