- ADC：24-bit Sigma Delta ADC.
- TPS: Internal Temperature Sensor.
- OPAMP: R2R means Rail to Rail Amplifier.
- DAC: Digital to Analog Converter
- BIA Module: It can generate AC waveform and measure the impedance and angle of the object to be measured.
- IRQ Function: When the ADC is interrupted, the IRQ interrupt signal can be output through the CLKOUT pin or the SDA pin.
