    DC Linear Gain Amplification

    I have a few TL071s  would those work good. If not what would you suggest. Regards Dennis

    DC Linear Gain Amplification

    I need a direct current linear amplifyer that with give me a gain of 10 from 1mv to 100 mv. Output inpedance > 10kohms  VCC 5 volts Vee -5 volts So far I have tried both a 741 and 324 opamp and both have problems below 40mv. Any ideas would be appreciated Regards Dennis

    digital voltmeter build confirmed

    MP The Only reason I changed the 180k to 100k was because both the intersil and maxim datasheets for the 7107 call for 100k resistor so I subed them into a prototype when I made it and it worked correctly so I left it in the final version. Regards Dennis

    digital voltmeter build confirmed

    Moderator I posted this thread here instead of the long thread about the digital voltmeter in hopes that it may inspire someone to build it. If you choose to move it I understand after reading the entire thread I thought that someone might like to know that the schematic and project works...

    max038 project using Eagle 4.15

    Im working on a function generator using the max038 IC Picture below \ The question is when I go to the board and auto generate the nets. Is there any tried and true way to place the components so as to minimize extranious routes along the circuit board Also below is a link to the above sch...

    Sine Wave Output on the IC8038 Circuit

    A TL071 is similar to an LF351 opamp since they both have difficulty with signals over 100kHz. 1MHz is a radio frequency so long wires can ruin the performance of your project. The parts on your perf board are very far apart causing series inductance in the long wires between parts. Capacitance...

    Sine Wave Output on the IC8038 Circuit

    Actually I replaced it with the TL071 ? I did look at the datasheets and knew distortion increased over 200khz or so. I just wondered if the ringing would be considered part of the THD or something else. Thanks for the welcome. I do plan on a project using the max038 chip along with the...

    Sine Wave Output on the IC8038 Circuit

    I built the Function Generator listed in the Projects using the ICL8038 Chip and have some problems with distortion at the High end of the frequency range 1Mhz. Below are a couple of pictures of the completed project and also a screenshot of the Scope image showing the ringing at the voltage...
