By examining the block diagram in Figure 5, we see
that the
maximum
current through pin Iout is set by fix-
ing values for V(VRef) and R. The output current can
then be varied by changing the data byte at the D/A
converter input.
In general, the magnitude of the current at the D/A
converter output pin may be calculated by:
I = (V(VRef) / (384 R)) N
where N is the decimal representation of the input byte
to the corresponding D/A converter.
The value for the resistor determines the
full scale out-
put
current that the D/A converter may sink or source.
Bits IFSO1 and IFSO0 select the full scale output cur-
rent setting for Iout as described in “IFSO1 - IFSO0:
Current Generator Full Scale Output Set Bits (Non-vol-
atile)” on page 12.
Bit IDS and in Control Register 0 select the direction of
the currents through pins Iout (See “IDS: Current Gen-
erator Direction Select Bit (Non-volatile)” on page 10
and “Control and Status Register Format” on
page 11).
D/A Converter Output Current Response
When the D/A converter input data byte changes by
an arbitrary number of bits, the output current changes
from an intial current level (I
x
) to some final level
(I
x
+
I
x
). The transition is monotonic and glitchless.
D/A Converter Control
The data byte inputs of the D/A converters can be con-
trolled in three ways:
– 1) With the A/D converter and through the look-up
tables (default),
– 2) Bypassing the A/D converter and directly access-
ing the look-up tables,
– 3) Bypassing both the A/D converter and look-up
tables, and directly setting the D/A converter input
byte.
