ADS1260-Q1: 2 AD channels can be rotated simultaneously

Part Number: ADS1260-Q1

hi,

Can two channels AD be switched at the same time?

Thanks!

  • Hi Neal,

    Are you asking if the MUXP and MUXN signals (in a single ADS1260-Q1 device) switch at the same time, or if two ADS1260-Q1 devices connected to the same SPI buss can switch MUX channels at the same time?

    • The MUXP and MUXN signals switch at the same time, after completing a WREG operation to the INPMUX register.

      alternately...

    • If two ADS1260-Q1's are operated off of the same external CLK (connected to CLKIN) and connected to the same SPI peripheral, then it is possible to "broadcast" a WREG command to both ADCs at the same time.

      If the ADCs are not operating off of the same CLK, then I would recommend switching the MUX channels independently and using the START pin to re-start the ADC conversions at around the same time. If there is no shared external clock then theses devices will not be exactly in sync.
