ADS1220: Similar device

Part Number: ADS1220

 Hello Team,

Can you suggest as similar specification to ADS1220  but has lower Iq, better precision and low power since the device will sleep 99% of the time. 

Regards,

Renan

  • Hi Renan,

    do you know what the ADC requirements are or what signals need to be measured?
    Would a 16-bit ADC be sufficient for example?

    If the ADS1220 is sleeping for 99% of the time I would actually suggest to cut the power to the ADS1220 completely. The ADS1220 is quite unique in a way that it powers up very quickly and that the internal voltage reference is stable after very short time. This makes the ADS1220 ideal for applications where you want to power-cycle the device. The downside to power-cycling is that you need to write the registers after every power up again. But the ADS1220 only has four registers, which should make it fairly quick to configure.

    Regards,
