ADS8588S: Need Similar part with some advancements

Aswin S Dharman
Prodigy 50 points

Part Number: ADS8588S
Other Parts Discussed in Thread: ADS9324, ADS9308V8I

Need a exactly similar features of the above mentioned part(ADS8588S )- Accuraccy, precision, simultaneous sampling and so on . But need 16 bit 16 Channel part(16 Channel should sample simontaneously). and should support SPI(SPI Only is preferable- Since IC Size and price matters).

 

So primarly I need to measure all 32 channels simultaneously(Current measured across the shunt and connected to the INA device from that it goes to the ADC ) 

Speed 20Ksps minimum, and the whole 32 channels should be read with in 20S(Capture Time)

    Hi Aswin S Dharman,

    The apps engineer who supports this device is on vacation now, please expect a delay in response.

    BR,

    Hi Aswin,

    Thanks for your post and your patience. Could you please share what kind of application/project you are working on so I can better understand your needs? We received this similar post. Is your post regarding the same project?  ADS8688: Digital Input to ADC 

    We do have a new 16-bit, 16CH, 1MSPS/CH ADC that is compatible with SPI: ADS9324. An evaluation module, ADS9324EVM, is also available for your easy evaluation when used with the TSWDC155EVM controller card and provided GUI.

    We do have an upcoming device ADS9308V8I (24-bit, 16CH, 250ksps/CH), which has the same pin out as ADS9324, but the upper 8 channels have an integrated INA to enable current measurements, like the lower 8 channels have an integrated PGA to enable to voltage measurements. We have samples available now. If this is appealing, please let me know and I can share the datasheet via email.

    Best regards,
    Samiha

    I would like to measure the current accurately through INA devices, and it need to be read with in 20s for all 64 channels, so it should be simultaneous sampled, and the sampling rate should be with in 10KS/S-20KS/S. But what ever I found where high cost components, I need a part which meets these requirements along with SPI interface and low cost (for 100nos- less than 10 dollars or less )
