Hello Gustavo.Castro
I'm pretty new in the forum I don't have much experience in fact this is my first cuestion in the forum, I was wondering if you could help me to find a sollution a similar problem that Lionelwallace has exposed time ago.
I need to digitize the output of a strain gauge. Their power source normally will be close to 3.6 but it should be possible use a step up for use with 5 v the consumption is critically I mean must be very, very low consumption this circuit need the positive swing only, and the resollution must be at least 10 bits Ideally 12, SPI output. The maximum sample rate is 15ms.
Could you please help me to find a sollution
Thanks in advance.
