Features
Brief Description
•
•
Low cost, precision temperature sensor
Single-wire 11-bit digital serial signal output
compatible with state-of-the-art µP controllers
Communication range > 10 meters
Resolution: 0.1ºC
The TSic temperature sensor IC family are fully test-
ed 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.

Accuracy: 0.3ºC over a span of ꢀ0ꢁC
The TSic 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.
Wide measurement range: –50 to +150 ºC
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 ( 10ꢂ) power supplies
•
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 (V+ = 2.97V
to 5.5V) or ratiometric (10~90ꢂ of V+; i.e.,
0.5~4.5Vout @ V+ = 5V) or the digital serial output
signal for interfacing with µP controllers.

Package: ꢀ-pin SOIC
Low quiescent current: <ꢀ0µA at 25ꢁC 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)
