AUTO-DAC ADJUSTMENT
In adaptive threshold mode, the part can dynamically adjust the
CAPDAC to keep the CDC in an optimal operating capacitive
range. When the auto-DAC function is enabled, the CAPDAC
value is automatically incremented when the data average
exceeds of the CDC full range (average > 0xA800), and
the CAPDAC value is decremented when the data average
goes below of the CDC full range (average < 0x5800).
The auto-DAC increment or decrement step depends on
the selected CDC capacitive input range (see the Setup Registers
section).
When the CAPDAC value reaches 0, the threshold for further
decrementing is ignored. Similarly, when the CAPDAC value
reaches its full range, the threshold is ignored. The CDC and
the rest of the algorithm are continuously working, and they are
functional down to a capacitance input of 0 pF or as high as the
capacitance input of (CAPDAC full range + CDC full range),
respectively.
POWER-DOWN TIMER
In power sensitive applications, the AD7156 can be set to
automatically enter power-down mode after a programmed
period of time in which the outputs have not been activated.
The AD7156 can then be returned to a normal operational
mode either via the serial interface or by the power supply
off/on sequence.
