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: better than 0.1ºC
Accuracy: ±0.5ºC at room temperature;
o
±1.0 C over span of 40°C
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 (±10%) power supplies
Package: 8-pin SOIC
Low quiescent current: <80µA at 25°C 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™ 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.
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.
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 cali-
brate 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 (10~90% of V+; i.e., 0.5~4.5Vout
@ V+ = 5V) or the digital serial output signal for
interfacing with
µP
controllers.
