简 介:IZ8016 3.5 DIGIT THERMOMETER
DESCRIPTION The IZ8016 is a CMOS circuit provided with digital thermometer function. Temperature reading from –50oC to +50oC is detected by use of a thermistor as a sensor and temperature is displayed on a LCD by 0.2oC step. High accuracy is obtained in wide range of –50oC ~ +50oC by providing non-linear correction circuit on the chip. FEATURES Measurement accuracy: ± 1oC Resolution : 0.2oC (oF) 31/2 + 7 Indicators, 31/2 duty LCD Low power consumption Few external components Easiness in adjustment Single 1.5V battery operation Package Type: Bare chip FUNCTIONS Measurable temperature range –49oC ~ +49.8oC -57oF ~ +121.8oF Suitable Thermistor RT=10K ± 1% (at 25oC) Sampling Cycle 1 seconds, 3 seconds, 5 seconds, 10 seconds (Default 10 sec) Oscillation Frequency 32.768 kHz Temperature adjustment: Adjustment of temperature is made by adjusting fundamental resistance against dispersion in resistance values of thermistors
