Medical ECG low power/low distortion DIP Op amp

I have been having trouble choosing an appropriate op amp package that meets the criteria stated in the tittle of this thread. Most of the op amps recommended in the medical applications section of this website are SO packages and too small to use in prototyping breadboard. Any suggestions or advice on choosing a particular model ? The functions required are for the Right leg driver and filtering of the ECG. I already have an instrumentation amplifier

  • Breadboards aren't really suitable for performance analogue works, so I usually get a quick and dirty 2 layer PCB made for prototyping. I get them for less than £100, which compares well for engineering time and you get results you can trust. It's easy to hand solder SOIC chips and 0805 passives, and with a bit of practice you can do 0.65mm lead pitch ICs and 0603 passives. I still find 0.5mm pitch packages and 0402 passives a bit tricky.

    The mindset that 'you can't prototype SMT' is probably your biggest stumbling block.
