FUNCTIONAL DESCRIPTION
(Continued)
Analog-to-Digital Converter
The Analog-to-Digital (ADC) is an 8-bit half flash converter
that uses two reference resistor ladders for its upper 4 bits
(MSBs) and lower 4 bits (LSBs) conversion. Two reference
voltage pins, AV
CC
and A
GND
, are provided for external
reference voltage supplies. During the sampling period
from one of the eight channel inputs, the converter is also
being auto-zeroed before starting the conversion. The
conversion time is dependent on the internal clock fre-
quency. The minimum conversion time is 35 x SCLK (see
Figure 22).
The ADC is controlled by the Z8 and its three registers (two
Control and one Result) are mapped into the Extended
Register File. A conversion can be initiated by writing to
the ADC Control Register 0 after the ADC Control Register
1 is configured.
The start command is implemented in such a way as to be-
gin a conversion at any time, if a conversion is in progress
and a new start command is received, then the conversion
in progress will be aborted and a new conversion will be
initiated. This allows the programmed values to be
changed without affecting a conversion-in-progress. The
new values will take effect only after a new start command
is received.
The ADC can be disabled (for low power) or enabled by a
Control Register bit.
Though the ADC will function for a smaller input voltage
and voltage reference, the noise and offsets remain con-
stant over the specified electrical range. The errors of the
converter will increase and the conversion time may also
take slightly longer due to smaller input signals.
ADC Calibration Offset
Specially matched resistors are program-enabled to allow
35 percent or 50 percent offset from A
GND
. They may se-
lectively enable these resistors to offset the A
GND
by 50
percent (2.5V to 5V) or 35 percent (1.75V to 5V) thereby
allowing the 8-bit ADC across a narrower voltage range.
This will allow significant resolution improvement within
the reduced voltage range.
Note:
The AV
CC
must be the same value as V
CC
and
A
GND
must be the same value as GND.
