TSic™- 306
High Precision, Rapid Response, Low Cost Temperature Sensor IC
Feature Sheet
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: 0.1ºC
• Accuracy: ±0.3ºC over a span of 80°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
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 (10~90% 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
• Very low power consumption – ideal for
mobile and standard applications
• Field reconfiguration/recalibration option
available (high volume customers only)
• Outstanding long term stability
