Study of Op – Amp. Math–Circuits, Model – 741 M.(using Op-Amp. as Summer, Substractor, Integrator, Differential)

Features  :

  • This experimental board  is designed  to study of few math validation (as a Summer, Subtractor,  Integrator and  Differentiator)  using  an  Operational  Amplifier – mA.
  • Builtin Regulated and Short circuit proof ± 12 Volt DC Power Supply suitable to  the  operational  board  and  Op – amp. 
  • Circuit is engraved and necessary network of Resistance and Capacitor  are mounted on the top of the decorated bakelite  sheet  to  facilitate  better  and  clear  understanding.
  • A  complete  working  manual  containing  theory,  circuit  details  and  operating  instruction  provided.
  • Stackable  type  connecting  leads  suitable  to  the  terminals  are  supplied  with  the  board  for  easy  inter – connections  and  longer  working  life  of  the  terminals.
  • The  board  has  builtin  is  symmetrical  ±  2, Volt  (Variable)  and  +  2 Volt  (Constant)  D.C.  Power  Supply  as  a  voltage  source  for  experimental  purpose.
  • One  D.P.M.  is  also  provided  with  the  board  for  measuring  output  voltages.
