Look-Up Tables
The X96012 memory array contains two 64-byte look-up
tables. One is associated to pin I1’s output current generator
and the other to pin I2’s output current generator, through
their corresponding D/A converters. The output of each
look-up table is the byte contained in the selected row. By
default these bytes are the inputs to the D/A converters
driving pins I1 and I2.
The byte address of the selected row is obtained by adding
the look-up table base address (90h for LUT1, and D0h for
LUT2) and the appropriate row selection bits. See Figure 9.
By default, the look-up table selection bits are the 6
MSBs of the A/D converter output. Alternatively, the A/D
converter can be bypassed and the six row selection bits
are the six LSBs of Control Registers 1 and 2, for the
LUT1 and LUT2 respectively. The selection between
these options is illustrated in Figure 10, and described in
Current Generator Block
The Current Generator pins I1 and I2 are outputs of two
independent current mode D/A converters.
D/A Converter Operation
The Block Diagram for each of the D/A converters is shown
in Figure 8.
The input byte of the D/A converter selects a voltage on the
non-inverting input of an operational amplifier. The output of
the amplifier drives the gate of a FET, whose source is
connected to ground via resistor R1 or R2. This node is also
fed back to the inverting input of the amplifier. The drain of
the FET is connected to the output current pin (I1 or I2) via a
“polarity select” circuit block.
