IC compatibility

Hi everyone!

 

We are building a pulse oximeter for our final year project. We found this application note in Analog devices website

 

http://www.analog.com/en/content/photodiode_sensing_in_pulse_oximeters/fca.html

 

But the ICs mentioned have their supply voltage range from 5V to 16V. Other ICs in our circuit have their operating voltages in the range 3V-less than 5V. We are using a blackfin processor too.

 

Can you please suggest op amps similar to AD8663/AD8667/AD8669 with operating voltage in the range we require?

 

Thanks in advance.
