IZ8016
3.5 DIGIT THERMOMETER
DESCRIPTION
The IZ8016 is a CMOS circuit provided with digital thermometer function. Temperature reading
from –50^oC to +50^oC is detected
by use of a thermistor as a sensor and temperature is displayed on a LCD by 0.2^oC step. High
accuracy is obtained in wide range of
–50^oC ~ +50^oC by providing non-linear correction circuit on the chip.
FEATURES
• Measurement accuracy: ± 1^oC
• Resolution : 0.2^oC (^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 –49^oC ~
+49.8^oC
-57^oF ~ +121.8^oF
• Suitable Thermistor RT=10KΩ ± 1% (at
25^oC)
• 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
