DS1821 Overview
For safety reasons, these analog sensors are packaged in the Bulk. To prevent damage to the analog sensors, they are packaged in TO-226-3, TO-92-3 Long Body packages. For proper operation, this sensor has 3 pins. Analog sensors could supply 1 mA current when operating. DC circuit should have a maximum voltage of 5.5 V. The minimum voltage supplied by this magnetic switch can be 2.7 V in a DC circuit, however. In theory, this sensor can be powered by 500 µA current. For optimal performance, the sensor's current output should be 4 mA. It is possible to set the maximum operating temperature for analog sensors to 125 °C. In order for this sensor to work, the operating temperature should not be lower than -55 °C.
