I want to design a summing amplifier to sum up four AC signals (3 Vpp each) of same freq but very low.

Signals are from 4 diff sensors and so the frequency of the signals can vary from 1 Hz to 100 Hz.

Low noise is also critical for the application.

can someone suggest me which opamp IC from analog device would be perfect for this application. 

Thank you in adavnce,
