Description
Full Shutdown Mode. In this mode, all internal circuitry on the AD7321 is powered down. Information in the control register
is retained when the AD7321 is in full shutdown mode.
Autoshutdown Mode. The AD7321 enters autoshutdown on the 15
All internal circuitry is powered down in autoshutdown.
Autostandby Mode. In this mode, all internal circuitry is powered down, excluding the internal reference. The AD7321 enters
autostandby mode on the 15
Normal Mode. All internal circuitry is powered up at all times.
Description
The channel sequencer is not used. The analog channel, selected by programming the ADD0 bit in the control register,
selects the next channel for conversion.
This configuration is used in conjunction with the channel address bit in the control register. This allows continuous
conversions on a consecutive sequence of channels, from Channel 0 through a final channel selected by the channel
address bit in the control register. The range for each channel defaults to the range previously written into the range
register.
The channel sequencer is not used. The analog channel, selected by programming the ADD0 bit in the control register,
selects the next channel for conversion.
