TSic Family
The TSic temperature sensor IC family are fully
tested and calibrated sensors with absolute
measurement accuracy on delivery – no further
calibration needed. The TSic combines
outstanding accuracy with long term stability, yet
it is very simple to use.
The TSic series is specifically designed for high
performance, cost-effective solutions for sensing
temperature in building automation, automotive,
industrial, office automation, white goods and
low-power/mobile applications.
TSic employs a high precision bandgap
reference with PTAT output; a low-power,
precision ADC; and an on-chip DSP core with
EEPROM to precisely calibrate the output
temperature signal. The TSic series includes
ICs with two linear analog signal output options,
such as standard 0~1Vout (Supply voltage (V+) =
3.0V to 5.5V) or ratiometric (10~90% of supply
voltage); or the digital serial output signal for
interfacing with microcontrollers.
Benefits
•
Several accuracy classes available with
100% upward compatibility
•
No calibration by customer needed;
absolute calibration specified
•
Simple to integrate, reducing cost and time
for application-development
•
Fast data measurement – optimal for
temperature control
•
Packages for standard SMD, THT or
application specific assembly
•
Miniaturized solutions with Bare-Chip
(COB, COF, CSP*) or e-line packages –
very fast response time for COF
•
Very low power consumption – ideal for
mobile and standard applications
•
Field reconfiguration/recalibration option
available (high volume customers only)
•
Outstanding long term stability
* COB: Chip-On-Board; COF: Chip-On-Flex; CSP: Chip Scale Packaging

Accuracy = specification plus quantization error of
1 bit (0.1°C). This device gets calibrated at 5V. For
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, 2σvalue.
Other TSic products with customer specific calibration
available on request: i.e. with special calibration where
the 80°C 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: ±0.1°C; T3: ±3°C
