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

Description TSic
TM
Series
The TSic
TM
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.
The TSic
TM
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.
TSic
TM
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
P
controllers.

Formula for Temperature Signal [C]:
Analog output 0-1V:
T = (Sig[Volt]*(HT-LT)+LT) [C]
Ratiometric 10%-90% output:
T = ((Sig[V]/VDD[V])-0.1)/0.8 *(HT-LT)+LT
Digital output:
T= (Digital_signal/2047*(HT-LT)+LT) [C]

Accuracy = specification plus quantization error of
1 bit (0.1C). This device gets calibrated at 5V. F or
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, 2
value.
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.
Temperature range limits T1, T2: 0.1C; T3: 3C
