Basic OpAmp Calculator For Voltage Gain
(Best if viewed in 800X600 or higher resolution)

Input parameters:

Inverting
Amp (A)

Rin: k Ohm
Rf: k Ohm

Non-Inv.
Amp (B)

Rin: k Ohm
Rf: k Ohm

Calculate:


Output results - Amp-A:
Inverted Gain = -
Output results - Amp-B:
Non-Inv. Gain =

Note: For proper action, the input
of the non-inverting opamp should
be referenced to ground if using a
bipolar supply. If V- is ground, then
the input resistor must be referenced
to 1/2 V+.
Refer to Nifty Opamp Circuits for
actual applications.

To convert to db,
db = (Vg)log X 20

also

db = 20 log Eout/Ein
or
(Eout/Ein)log X 20
