button cell selection issue

Hi all,

I am trying to build a portable wireless EEG system using ADS1299. The analog supply voltage and current of ADS1299 are 4.75~5.25V and 7.14mA respectively. And for the control and wireless MCU I am considering CC2650 (1.8~3.8V, 6.1 mA @ Active-mode TX ). I think the current supply of the whole system should be more than 30mA taking other components into consideration. The system is size critical so the smaller battery size the better, and the system should last at least 10 hours hopefully. I don't know very much about batteries, is there any suggestion on which battery should be used?

I found these batteries:

http://media.digikey.com/pdf/Data%20Sheets/FDK/2CR-1-3N.pdf


They both can provide max 60mA current continuously.

Are there any other batteries more suitable(same capacity with smaller size or same size with larger capacity) for my system?

Thanks!

Regards,

Eric

    In general we can not recommend a battery for an application. If your distributor is unable to provide suitable options you might contact a cell manufacturer for guidance.
