Hi Netters:

I am new in electronics land, so please be gentle....
I have a question. I want to a build an integrator (an opamp based) but I
heard horror things about opamps voffset and stuff. So any improvement on
the following circuit is much appreciated.


              +-------R2-----------+
              |                    |
              +-------C------------+
              |                    |
              |    |\  +-- +Vs     |
              |    | \ |           |
              |    |  \|           |
              |    |   \           |
 Vin ----R1---+----| -  \          |
                   |     \---------+ Vout
                   |     /
              +----| +  /
              |    |   /
             GND   |  /|               R2 >> R1
                   | / +-- -Vs
                   |/

1. I don't need an opamp with awesome slew rate to make an integrator, right?
2. How do I deal with Voffset problem.
3. This is going to be used in a high precision, low noise data acquisition.
   The professor I work for doesn't know anything about electronics, but he
   WANTS LOWEST POSSIBLE noise. What opamp should I use for Vinput with band
   width of about 500kHz. The circuit is NOT a power circuit.

Please email reply. Thanks in advance. Hope I can learn more about electronics
and contribute to the group in the future.
