Power-Down
Timeout
Defines the period duration of the power-down timeout.
If the output comparator output has not been activated during the programmed period, the part enters power-
down mode automatically. The part can be then returned to a normal operational mode either via the serial
interface or by the power supply off/on sequence.
The period is programmable in steps of four hours. For example, setting the value to 0x06 sets the duration to
24 hours. The maximum value of 0x3F corresponds to approximately 10.5 days.
The value of 0x00 disables the power-down timeout, and the part does not enter power-down mode
automatically.

Description
7
DacEn
DacEn = 1 enables capacitive DAC.
6
DacAuto
DacAuto = 1 enables the AutoDAC function in the adaptive threshold mode.
When the AutoDAC function is enabled, the part dynamically adjusts the CAPDAC to keep the CDC in an
optimal operating capacitive range. The CAPDAC value is automatically incremented when the data average
exceeds of the CDC full range, and the CAPDAC value is decremented when the data average goes below
of the CDC full range. The AutoDAC increment or decrement step depends on the selected CDC capacitive
input range.
Bit has no effect in fixed threshold mode; the AutoDAC function is always disabled in the fixed threshold mode.

DacValue
CAPDAC value, Code 0x00
≈ 0 pF, Code 0x3F ≈ CAPDAC full range.
SERIAL NUMBER REGISTER

This register holds a serial number, unique for each individual part.
CHIP ID REGISTER
Address Pointer 0x17
8 Bits, Read Only, 0xXX
This register holds the chip identification code, used in factory
manufacturing and testing.
