ZoomingADC for sensing data acquisition

6 General Description
The SX8724C is a complete low-power acquisition path with programmable gain, acquisition speed and resolution.
6.1 Bloc diagram
6.2 VREF
The internally generated VREF is a trimmed bandgap reference with a nominal value of 1.22V that provides a stable
voltage reference for the ZoomingADC.
This reference voltage is directly connected to one of the ZoomingADC reference multiplexer inputs.
The bandgap voltage stability is only guaranteed for VBATT voltages of 3V and above. As VBATT drops down to 2.4V, the
bandgap voltage could reduce by up to 50mV.
The bandgap has relatively weak output drive so it is recommended that if the bandgap is required as a signal input
then PGA1 must be enabled with gain = 1.
6.3 GPIO
The GPIO block is a multipurpose 4 bit input/output port. In addition to digital behavior, D0 and D1 pins can be
programmed as analog pins in order to be used as output (reference voltage monitoring) and input for an external
