The UCB1100 contains an on chip reference voltage source, which
generates the reference voltages for the 10 bit ADC and the
necessary internal reference voltages. Alternatively, the UCB1100
can be driven from an external reference voltage source.
On Chip Reference Circuit
The internal reference voltage can be monitored and filtered
additionally on the vrefbyp pin. Two bits in the ADC control register
determine the mode of operation of this reference voltage circuit.
The vrefbyp_conbit connects the internal reference voltage to the
vrefbyp pin, while the ext_vref_enabit disables the internal
reference voltage and switches the UCB1100 into the external
voltage reference mode.
The internal reference circuit is activated only when one or more
analogue functions inside the UCB1100 is activated. This reduces
the current consumption of the analogue part in standby mode. The
external reference voltage source is also disconnected when all
analogue functions are disabled.
