ANALOG
COMMON
Establishes the internal analog ground point. Analog common is set to 2.9V below the positive supply
by an internal zener reference circuit. The voltage difference beween V
DD
and analog-common can be
used to supply the TC826 voltage reference input at REF IN (Pin 5).
Positive analog signal input.
Negative analog signal input.
Reference voltage positive input. Measured relative ato analog-common. REF IN
Full-Scale/2.
Reference capacitor connection.
Reference capacitor connection.
Positive supply terminal.
Buffer output. Integration resistor connection.
Negative comparator input. Auto-zero capacitor connection.
Integrator output. Integration capacitor connection.
Negative supply terminal.
Oscillator resistor (ROSC) connection.
