Hello TI,

I need a circuit design for a 2 Lead Dry contact electrode ECG system. I am selecting INAMP & OPAMP for the design. Please suggest me a very good working circuit & IC'S. Please I am not preferring ADSXXXX series.

My requirements are as fallows,

1. It is a handheld equipment with battery powered, so the power consumption should be less.

2. The production quantity is 2000 piece/month, so the cost of the chip & circuit should be very less.

3. The circuit should have very good reliability & repeatability.

3. The electrodes contact with thump [dry contact], so the sensitivity should be linear for all type of skins.

Please provide me necessary support to start my project....

Thanks & regards
