Standby operating mode

The internal IOVDD LDO regulator is disabled.

100 μs

If IOVDD is not externally supplied, all GPIOx and all

LVDS data interface and SPI data interface signals

are disabled. For the SPI configuration interface only.

writes to the device configuration register (see the

Device Configuration Register section) and Interface

Configuration A register (see the Interface Configuration

A Register section) are allowed.

If IOVDD is externally supplied, all GPIOx and SPI data

interface signals are enabled. The SPI configuration

interface is fully enabled. Because the SPI data

interface remains enabled, the user can access data

in the result FIFO (see the Result FIFO section).

The ADC core is powered down. The analog circuitry

remains in reset (ANA_RESET remains asserted), and

no ADC conversions can be performed.

The VDD33 supply can be removed to reduce power.

When in use, the internal VDD11 LDO regulator remains

on.

The internal reference buffer is enabled.

Common-mode output buffer is enabled.

The LVDS interface is disabled.
