0V-power supply for analog part
digital power input for programming Zener fuses.
0V-power supply and ground reference point for digital part
digital input for external clock, master clock input
serial port clock input for SDI-port
serial data in- and output
Digital I/O for interrupt from comparator
conversion ready flag for external interupt and synchronisation
+ 5V digital power supply
+ 5V analog power supply
reference input/output
analog ground, ground reference for ADC
analog input with reference to RSHL
analog output for current-source
must be connected to VSS with a 30 nF capacitor
this PIN must be connected with a 50-100nF-capacitor to VSS;
no direct connection to VSSD/VSS allowed
signal wake-up to external µC
in normal mode
external clock typical 8.192 MHz; during MWU-mode external
connection must be high impedance or connected to VDDD to
reduce current consumption
the user must provide a serial clock on this input
This input must be open or connected to VDDD. It is not intended,
that OTP content is modified by the user.
