    I am making a device to read values from a Melexis MLX 90614 infra red temperature sensor to use with a racing car's data logger.
    The manufacturers provide an application note on how to read the PWM stream and convert it to an analogue voltage, which is what I need. The problem is that they recommend using a AD8603 or equivalent which is surface mount so I was looking for a DIP package for development purposes.
    Can anyone recommend a suitable amp that I can use on a breadboard or stripboard. It needs to work with a single +5V power supply and have low distortion, no phase reversal and be unity gain stable.
    Or better still, tell me how I would go about finding a suitable substitute?

    The NS LM358 comes in a DIP package and is designed to run off a single 5V supply. It will slew rail-to-rail. It is unity gain stable and comes in a dual op-amp package, the LM 324 is basically the same op-amp in a quad DIP package. Both these are fairly old and there may be better single supply amps from other manufacturers.
