Figure 7. A/D Converter Input Select Structure
A/D Converter Range
From Figure 6 we can see that the operating range of
the A/D converter input depends on the voltage refer-
ence. And from Figure 7 we see that the internal tem-
perature Sensor output also varies with the voltage
reference (VRef).
The table below summarizes the voltage range restric-
tions on the VSense and VRef pins in different configu-
rations :
VSense and VRef ranges
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 gen-
erator, 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 Fig-
ure 10, and described in “I2DS: Current Generator 2
Direction Select Bit (Non-volatile)” on page 13, and
“Control Register 2” on page 13.
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.
