• Provide 8-bit (1 ℃ resolution) temperature measurement values
• The accuracy is ± 1 ℃ within the range of 0 ℃~85 ℃
• Convert temperature to digital code words within 1 second (maximum)
• Available in 3-pin TO-92 package
2 . Application scenarios
• Temperature control
• Industrial systems
• Consumer goods
• Temperature gauge
• Any thermal sensing system
3 . Chip Overview
GX1821 can be used as an independent thermostat with user programmable trigger temperature points, or as an 8-bit temperature sensor with a single bus digital interface. The temperature point triggered by the thermostat is stored in non-volatile memory, so the GX1821 unit can be programmed before being connected to the system to achieve true independent operation. The working temperature range of GX1821 is -55 ℃ to+125 ℃, with an accuracy of ± 1 ℃ within the range of 0 ℃ to+85 ℃. Communication with GX1821 is achieved through the drain DQ pin; This pin is also used as a thermostat output.
