Practical Op-Amps HW

jav284
  1. Search the Internet for a LM741 datasheet. texas Instruments can be a good source.
  2. Answer the following questions:
  3. Given a signal with a peak voltage of 10V and a frequency of 2kHz, calculate the SR for Figure A.4, pg. 212.
  4. Given a total noise voltage of ent = 1mV, current noise In = 2pA/sqrt(Hz), and a source resistance Rs = 2kohms, calculate the voltage noise, Vn parameter.  Requires solving for Vn in equation (A.3), pg. 207.
  5. Given that the maximum frequency without distortion fmax is defined as fmax = SR/2piVp, calculate SR with fmax = 3kHz, and Vp-p = 15v.
  6. Review the “LM741 datasheet” in your course materials and provide the following information:
    1. Supply voltage range
    2. Input Offset Voltage (typical) and (max)
    3. Large Signal Voltage Gain (min) and (typical)
    4. CMRR (typical)
    5. SVRR (typical)
    6. SR (typical)
    7. How many BJT’s comprise the internal circuitry?
  7. Scan all work and save it for upload with the title: “HW3_StudentID”, with your student id substituted in the file name.  Show all work for full credit.
  8. Upload file “HW3_StudentID”
