In ENABLE-16 mode, the aux-DACs have independent
control bits E4, E5, and E6, and bit E9 enables the aux-
ADC. Table 7 shows the auxiliary DAC enable codes
and Table 8 shows the auxiliary ADC enable codes. Bits
E11 and E10 are reserved. Program bits E11 and E10 to
logic-low.
Modes aux-DAC1, aux-DAC2, and aux-DAC3 select
the aux-DAC channels named DAC1, DAC2, and
DAC3 and hold the data inputs for each DAC. Bits
_D11–_D0 are the data inputs for each aux-DAC and
can be programmed through SPI. The MAX19707 also
includes two 6-bit registers that can be programmed to
adjust the offsets for the Tx DAC I and Q channels
independently (see Table 9). Use the COMSEL mode
to select the output common-mode voltage with bits
CM1 and CM0 (see Table 10). Use Aux-ADC mode to
start the auxiliary ADC conversion (see the
10-Bit,
333ksps Auxiliary ADC
section for details). Use
ENABLE-8 mode for faster enable and switching
between shutdown, idle, and standby states as well as
switching between FAST, SLOW, and Rx and Tx modes.
