ADS1293: current consumption when RSTB is active

JAP

Part Number: ADS1293

Dear Experts,

Is there any existing data on ADS1293's current consumption when RSTB is active? Could not find that information from datasheet.

Thanks!

    Hello Juha,

    Thanks for supporting our ADS1293!

    I realize there is no documentation about that in the datasheet. I'll see what I can find out with bench measurements.

    Meanwhile, have you seen table 7? There is a detailed breakdown of the circuitry which powers down in Standby Mode and Power-Down Mode. These modes are set in the CONFIG (00h) register. Based on the amount of information in this table, I believe the intention is to use those register bits when placing the device in a low-power state. The RSTB pin, on the other hand, should probably only be used when you need to reset the digital core of the device (i.e. on power-up, an extra reset pulse is usually suggested). Pulsing the RSTB pin should clear the device registers, so they will need to be reconfigured.

    Best Regards,
