Single-chip CMOS construction Measurement range: 32.00°C ~42.99°C (90°F ~ 109.9°F) Measurement accuracy: ±0.1°C (±0.2°F) Resolution: 0.01°C (0.1°F) Single 1.5V battery operation Highest temperature hold Multi stable time selection: 4s/8s/16s/32s Automatic power off One ON/OFF switch input key Bonding option for °C and °F Display the last time measured temperature Interface to JAZTEK's Voice IC for Talking Thermometer Alarm warning for fever Buzzer output: 6k/8kHz JA31102/JA31103/JA31104 for 503ET sensor & JA31105 for 503FT sensor For various sensor application, change one layer only
General Description
The JA3110X are CMOS digital clinical thermometer IC for measuring body temperature from 32.00°C ~ 42.99°C (90°F ~ 109.9°F). It also provides stable alarm, fever alarm, automatic power off and the memory function of the last time measured temperature. The chip provides multi stable time selection for various of thermister also. The JA31103/JA31104 provides OEB and DATA output to interface with JAZTEK's Voice IC or MCU. This is an excellent solution for talking thermometer. The other required electronic components are LCD display, thermister, 1.5V battery, ON/OFF switch, buzzer, resistors and capacitors.
