Differential signal from Resistance  bridge(P3).  ADC is ADUC7060 Internal  .Consideration 4-20mA Circuit ,the power dissipation very low.Can only use ADA4051-2 Build Differential signal amplify. The scheme is ok?  In the debug,ADC1 ADC0 have 50HZ vpp 200mV Noise.Needs to go a step further filter?

How to filter out the noise(50Hz).
