5 Lead ECG

I went out to vist a customer that wanted to build a 5 lead ECG with PSoC3.  He figured he would need 14 op amps. I used two.
 
It exploits the ADCs resolution and filtering to allow a DC coupled front end.  Of course some MOVs or HV protection will be needed.

hey
thanks for this post.
all the resistors and capacitors are extern, aren't they? do you have a scheme with all values of these components? i'd really like to make a short test of this circuit.
best regards

Hello, Dave

would you be kind to explain what'll happens in you schematic when A_Mux_1 is in position 3?

Thanks in advance,

Vladimir
