Inverting Operational Amplifier kit.
The operational amplifier (op- amp) is a highly efficient monolithic integrated circuit. An amplifier has an input port and an output port. In a linear amplifier, output signal = A * (time) input signal, where A is the amplification factor or gain (positive or negative number). The Op-Amp has a very high gain, high input impedance, and DC coupled difference amplifier with a low impedance single ended output. An ideal op-amp, by itself, is not a very useful device since any finite input signal would result in infinite output. By connecting external resistors around the ideal op-amp, we construct useful amplifier circuits. The basic Inverting amplifier , so named because the input signal connected via resistor to the (-) the inverting input of the Op-Amp. The kit should be powered via 9V battery. Simply connect the battery (+) poll to the VCC, and the negative poll (-) to the Ground (GND).
Note: Vin1 or Vin2 should be smaller then (VCC-VSS-0.4V)
This kit contain dual (2) inverting Op-Amp "channel" configurations. Each which work independently of the other board and has its won adjustable gain trimmer (P1 and P2). However you can short those trimmers (JP1 and JP2) on the PCB if desire. One probably asks why? The answer is very simple. Use when you don't need high accuracy gain, or when you use high tolerance (percentage) 1% or 0.1% resistors.
The board gain is defined in the following formulas:
Where;
A1 = Gain Op-Amp #1
A2 = Gain Op-Amp #2
A1 = Vout1 / Vin1 = - (RY1 / (P1 + RX1)
A2 = Vout2 / Vin2 = - (RY1 / (P2 + RX2)
