AD5372/AD5373
Rev. C | Page 20 of 28
POWER-DOWN MODE
The AD5372/AD5373 can be powered down by setting Bit 0 in
the control register to 1. This turns off the DACs, thus reducing
the current consumption. The DAC outputs are connected to
their respective SIGGNDx potentials. The power-down mode
does not change the contents of the registers, and the DACs
return to their previous voltage when the power-down bit is
cleared to 0.
THERMAL SHUTDOWN FUNCTION
The AD5372/AD5373 can be programmed to shut down the
DACs if the temperature on the die exceeds 130°C. Setting Bit 1
in the control register to 1 enables this function (see Table 16).
If the die temperature exceeds 130°C, the AD5372/AD5373 enter
a thermal shutdown mode, which is equivalent to setting the
power-down bit in the control register to 1. To indicate that the
AD5372/AD5373 have entered thermal shutdown mode, Bit 4
of the control register is set to 1. The AD5372/AD5373 remain
in thermal shutdown mode, even if the die temperature falls,
until Bit 1 in the control register is cleared to 0.
TOGGLE MODE
The AD5372/AD5373 have two X2 registers per channel, X2A
and X2B, which can be used to switch the DAC output between
two levels with ease. This approach greatly reduces the overhead
required by a microprocessor, which would otherwise need to
write to each channel individually. When the user writes to the
X1A, X1B, M, or C register, the calculation engine takes a certain
amount of time to calculate the appropriate X2A or X2B value.
If an application, such as a data generator, requires that the
DAC output switch between two levels only, any method that
reduces the amount of calculation time necessary is advanta-
geous. For the data generator example, the user needs only to
set the high and low levels for each channel once by writing to
the X1A and X1B registers. The values of X2A and X2B are
calculated and stored in their respective registers. The calculation
delay, therefore, happens only during the setup phase, that is,
when programming the initial values. To toggle a DAC output
between the two levels, it is only required to write to the relevant
A/B select register to set the MUX2 register bit. Furthermore,
because there are eight MUX2 control bits per register, it is
possible to update eight channels with a single write. Table 10
shows the bits that correspond to each DAC output.
