TMP421AIDCNTG4 Overview

For safety reasons, these analog sensors are enclosed in the Tape & Reel (TR). To prevent damage to the analog sensors, they are packaged in SOT-23-8 packages. A sensor with 8 pins functions properly. It contains 8 terminations. As a result, the analog sensors could supply a current 32μA. Ideally, this sensor should provide a voltage of 5.5V in a DC circuit. However, the minimum voltage that this magnetic switch can supply in the DC circuit is 2.7V. For analog sensors, GND current should be 400μA. It is generally recommended that the current output of the sensor be 6mA for optimal performance.
