The MAX11120–MAX11128 feature three power-down
modes.
The devices shut down when the SPM bits in the ADC
Configuration register are asserted
two shutdown options:
U Full shutdown where all circuitry is shutdown.
U Partial shutdown where all circuitry is powered down

Static Shutdown
All circuitry is fully powered up at all times.
The device enters full shutdown mode at the end of each conversion. All circuitry
is powered down. The device powers up following the falling edge of CS. It takes 2
cycles before valid conversions take place. The information in the registers is retained.
The device powers down all circuitry except for the internal bias generator. The part

again at the following falling edge of CS. There are two
available options:
U AutoShutdown where all circuitry is shutdown.
U AutoStandby where all circuitry are powered down
The device shuts down after all conversions are complet-
ed. The device powers up again at the next falling edge
of CNVST or at the rising edge of CS after the SWCNV
bit is asserted.
