Features
Low cost, precision temperature sensor
Single-wire 11-bit digital serial signal output
compatible with state-of-the-art P controllers
Communication range > 10 meters
Resolution: 0.1C
Accuracy: 0.3C over a span of 80C
Wide measurement range: 50 to +150 C
Signal read-out every 0.1s (other rates available
on request)
V+ supply voltage: 2.97 to 5.5V (industry
standard); 3.3V or 5V (10%) power supplies
Package: 8-pin SOIC
Low quiescent current: <80A at 25C with 3.3V
minimizes self-heating errors for applications such
as wall-mounted thermostats
System-on-a-chip based on advanced mixed-
signal technology integrating precision tempera-
ture sensing bandgap reference with proportional-
to-absolute-temperature (PTAT) output, digital
signal processor (DSP) core, and electrically
erasable memory (EEPROM)

Brief Description
The TSic
TM
temperature sensor IC family are fully test-
ed and calibrated sensors with absolute measurement
accuracy on delivery no further calibration needed.
The TSic
TM
combines outstanding accuracy with long
term stability, yet it is very simple to use.
The TSic
TM
series is specifically designed for high per-
formance, cost-effective solutions for sensing temper-
ature in building automation, automotive, industrial,
office automation, white goods and low-power/mobile
applications.
TSic
TM
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
TM
series includes ICs with two linear analog signal
output options, such as standard 0~1Vout (V+ = 2.97V
to 5.5V) or ratiometric (10~90% of V+; i.e.,
0.5~4.5Vout @ V+ = 5V) or the digital serial output
signal for interfacing with
P controllers.
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 temper-
ature control
Packages for standard SMD, THT or applica-
tion specific assembly
Very low power consumption ideal for
mobile and standard applications
Field reconfiguration/recalibration option
available (high volume customers only)
Outstanding long term stability

1 With supply voltage 2.7V - 2.97V, accuracy is slightly
reduced; below 2.7V, functionality is unknown.
2 Output signal is limited to this ambient temperature (applies
to calibration, offset and gain).
3 When using the output as a digital output, the load capacitor
