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.
