TSic™- 206 Precise, Rapid Response, Low-Cost Temperature Sensor IC Feature Sheet 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 Accuracy: ±0.5ºC over a span of 80ºC 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 mixedsignal technology integrating precision temperature sensing bandgap reference with PTAT output; digital signal processor (DSP) core, and electrically erasable memory (EEPROM) The TSic temperature sensor IC family are fully tested 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 performance, cost-effective solutions for sensing temperature in building automation, automotive, industrial, office automation, white goods and low-power/mobile applications. TSic employs a high precision bandgap reference with proportional-to-absolute-temperature (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.
