By examining the block diagram in Figure 7, we see
that the maximum current through pin I1 is set by fixing
values for V(VRef) and R1. 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 pins (I1, I2) may be calculated by:
where x = 1,2 and N is the decimal representation of
the input byte to the corresponding D/A converter.
The value for the resistor Rx (x = 1,2) determines the
full scale output current that the D/A converter may
sink or source. The full scale output current has a
maximum value of ±3.2 mA, which is obtained using a
resistance of 255Ω for Rx. This resistance is con-
nected externally to pin Rx of the X96010.
Bits I1DS and I2DS in Control Register 0 select the
direction of the currents through pins I1 and I2 inde-
pendently (See “I1DS: Current Generator 1 Direction
Select Bit (Non-volatile)” on page 10 and “Control and
Status Register Format” on page 11).
The options are summarized in the following tables:

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

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
– 2) Bypassing the A/D converter and directly
– 3) Bypassing both the A/D converter and look-up
