are the data inputs for each aux-DAC and can be pro-
grammed through SPI. The MAX19708 also includes
two 6-bit registers that can be programmed to adjust
the offsets for the Tx path I and Q channels indepen-
dently (see Table 10). Use the COMSEL mode to select
the output common-mode voltage with bits CM1 and
CM0 (see Table 11). 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 shut-
down, idle, and standby states as well as switching
between FAST, SLOW, Rx and Tx modes.
Shutdown mode offers the most dramatic power sav-
ings by shutting down all the analog sections of the
MAX19708 and placing the Rx ADC digital outputs in
