Description
The channel sequencer is not used. The analog channel, selected by programming the ADD2 to ADD0 bits in the control
register, selects the next channel for conversion.
Uses the sequence of channels that were previously programmed in the sequence register for conversion. The AD7328
starts converting on the lowest channel in the sequence. The channels are converted in ascending order. If uninterrupted,
the AD7328 keeps converting the sequence. The range for each channel defaults to the range previously written into the
corresponding range register.
This configuration is used in conjunction with the channel address bits 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 bits in the
control register. The range for each channel defaults to the range previously written into the corresponding range register.
The channel sequencer is not used. The analog channel, selected by programming the ADD2 bit to ADD0 bit in the control
register, selects the next channel for conversion.
Description
Full shutdown mode. In this mode, all internal circuitry on the AD7328 is powered down. Information in the control
register is retained when the AD7328 is in full shutdown mode.
Autoshutdown mode. The AD7328 enters autoshutdown on the 15
updated. All internal circuitry is powered down in autoshutdown.
Autostandby mode. In this mode, all internal circuitry is powered down, excluding the internal reference. The AD7328
enters autostandby mode on the 15
Normal mode. All internal circuitry is powered up at all times.
