SIC4340 is NFC tag type 2 with built-in ADC for physical sensor measurement for 3-channels selectable. These built-in ADC can drive the current from 1 uA to 504 uA and measure the electrical value (e.g. voltage, resistance, and capacitance). The measured value is provided with 10-bit resolution. SIC4340 Tools application is developed to help the user learn how to use SIC4340 features with many sensors such as light sensor, gas sensor or temperature sensor. In this app, the user can set the bias current for each channel and measure the result from SIC4340 IC. The voltage and resistance result will be displayed on the app after measurement.
