Data Sheet
AD7699
Rev. B | Page 21 of 28
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
CFG[13:0] = 0x3FFF. This sets the AD7699 for the 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 sequencer
No readback of the CFG register
Table 8 summarizes the configuration register bit details. See
the Theory of Operation section for more details.
