Other Parts Discussed in Thread: ADS1282

Hi,

Can you please clarify these points

1) Can we keep SYNC input of ADS1282 permanently high in SPI mode of operation.

2) In read data Continuous mode How to select channels?

3) Or is it always one single channel in continuous mode ?

Regards,

Akshat

    1) Can we keep SYNC input of ADS1282 permanently high in SPI mode of operation. BB> If you do not need to use the functionality of the external SYNC pin, or to synchronize multiple devices then you can tie SYNC high.

    2) In read data Continuous mode How to select channels? BB> When you need to write a new configuration (such as changing MUX channels) you should issue the SDATAC command first.  See the SDATAC description on page 33 of the ADS1282 datasheet.

    3) Or is it always one single channel in continuous mode ?  BB> You can only convert on one channel at a time as there is only one ADC on this part with a mux that determines which input is selected.  The input is selected by writing the desired input channel in the CONFIG1 register (bits 4, 5 and 6).
