Table 5. Power Management Modes
Power-Down Mode
The MAX11129–MAX11132 feature three power-down
modes.
Static Shutdown
The devices shut down when the SPM bits in the ADC
Configuration register are asserted (Table 6). There are
two shutdown options:
U
Full shutdown where all circuitry is shutdown.
U
Partial shutdown where all circuitry is powered down
except for the internal bias generator.
AutoShutdown with External Clock Mode
When the PM_ bits in the ADC Mode Control register are
asserted (Table 5), the device shuts down at the rising
edge of CS in the next frame. The device powers up
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
except for the internal bias generator.
AutoShutdown with Internal Clock Mode
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.

AutoShutdown
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.

0
AutoStandby
The device powers down all circuitry except for the internal bias generator. The part
powers up following the falling edge of CS. It takes 2 cycles before valid conversions
take place. The information in the registers is retained.
