Typical sensitivity of the '2050 is only 0.8mV per kPa according to the datasheet. That equates to ~8mV per metre of water depth by my reckoning. IMO you'd need a good instrumentation amp to get a suitable signal for input to the micro.
So can you purpose an instrument amplifier for this application ?? I have seen the INA111 but can I replace it by the TL074 and I sae the same configuration ??
