Remark:
ADC:24-bit Sigma Delta ADC。
TPS: Internal Temperature Sensor.
OPAMP: R2R means Rail to Rail Amplifier.
DAC: Digital to Analog Converter.
Waveform Generator: Combine with DAC and OPAMP to output arbitrary waveforms.
IRQ Function: When the ADC is interrupted, the IRQ interrupt signal can be output through the CLKOUT pin or the SDA pin.
