Features

•

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;

±1.0

•

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.

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

•

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
