Voltage follower Operational Amplifier (buffer) 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 voltage follower amplifier, so named because the output signal is equal to the input one. Use where one wants to measure voltage with minimum drawing of current (buffer), or where one voltage output feeds many inputs.

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 than (VCC-VSS-0.4V)

This kit contains dual (2) inverting Op-Amp "channel" configurations. Each works independently of the other and has its own current eliminator resistor (RX1 and RX2). However, you can short those resistors (RX1 and RX2) on the PCB if desired. 

The board gain is defined in the following formulas:

A1 = Vout1 / Vin1 = 1 (unity gain)

A2 = Vout2 / Vin2 = 1 (unity gain)
