Hello all,
In need some help about power consumption using PGA280 and ADS1259. Datasheet is not so clear about this topic, only providing quiescent current.
I'm using:
VSP = +15V
VSN = -15V
VSOP = +2,5V
VSON = -2,5V
DVDD = +5V
What will be the worst consumption using this power rails ?
Hi Mateus,
Current consumption is going to be dependent on a variety of options/settings within both the PGA280 and ADS1259. You can look at the quiescent current for the PGA280 and the current consumption of the ADS1259 in their respective data sheets to get a baseline. My recommendation is to order an ADS1259EVM-PDK as it comes complete with an on board PGA280 and software for analysis. This will allow you to set up the devices as you would like and use a DMM to monitor the current drawn during various settings.
Regards,
