    CA3130A and CA3130 are op amps that combine the advantage of both CMOS and bipolar transistors. Gate-protected P-Channel MOSFET (PMOS) transistors are used in the input circuit to provide very-high-input impedance, very-low-input current, and exceptional speed performance. The use of PMOS transistors in the input stage results in common-mode input-voltage capability down to 0.5V below the negative-supply terminal, an important attribute in single-supply applications.

    The CA3130 Series circuits operate at supply voltages ranging from 5V to 16V, (±2.5V to ±8V). They can be phase compensated with a single external capacitor, and have terminals for adjustment of offset voltage for applications requiring offset-null capability. Terminal provisions are also made to permit strobing of the output stage. The CA3130A offers superior input characteristics over those of the CA3130.

        Hi Nader, What circuit are you referring to or what function do you need? This op amp has many applications.

    21. hi sir can anybody tell me please what is the appr cost of this projec please……

    22. where in bangalorecan i find dis circuit..
      reply soon…

    23. sir, i want 2 knw abt antenna..pls guide me…

    24. sir what are other alternatives for IC 3130

    25. i want to know how can we make antenna for this project from a wire….i got a problem….i have used this circuit but buzer beeps as soon as switch is on…plz help me solve ir…reply asap

    26. Sir I am a student of school in class 11 but I am relly intrested in making circuits I made many of them by presently I am making this cellphone detector but I am not able to find CA3130 ic op amp plss tell me any two alternatives

    27. i want the project report of mobile detector usig ic ca3130 and 555

    28. i am trying to make it.. but need little help.. the cicuit is complete and led is on but its not detecting.. what i can do to make it work???

    29. Can it be replaced by CA3440AE or CA3440M

    30. I want to know that,is ic 741 do substitute for ic 3130 or ic 3140 on cell phone detecting project. Please sir, do replay on my mail with full configuration. Thank u.
