Data Sheet
AD7682/AD7689
Rev. D | Page 25 of 32
The register can be written to during conversion, during acquisi-
tion, or spanning acquisition/conversion, and is updated at the end
of conversion, tCONV (maximum). There is always a one deep
delay when writing the CFG register. Note that, at power-up, the
CFG register is undefined and two dummy conversions are
required to update the register. To preload the CFG register with a
factory setting, hold DIN high for two conversions. Thus
following:
IN[7:0] unipolar referenced to GND, sequenced in order
Full bandwidth for a one-pole filter
Internal reference/temperature sensor disabled, buffer
enabled
Enables the internal sequencer
No readback of the CFG register
Table 10 summarizes the configuration register bit details. See
the Theory of Operation section for more details.
