Single-Ended Op Amp and Fully Differential Op Amp circuit symbols

This page covers Single-Ended Op Amp and Fully Differential Op Amp. It mentions Single Ended to Differential Conversion Operational Amplifier circuit.

single ended and differential circuit symbol

As shown in the figure-1, single ended Op-Amps will have two inputs viz. positive and negative. They have single output, which is referenced to system GND.

The differential op-amp has two power supply inputs which are connected to positive as well as negative voltages. The output is fully differential with one positive and other negative. The outputs are differential similar to inputs. The output voltages are equal and opposite in polarity.

Single Ended to Differential Conversion Op-Amplifier circuit

single ended to differential conversion circuit

The figure-2 depicts single ended to differential conversion circuit. This conversion is needed to connect op-amplifier with differential input of ADC converter.

The left one is called inverting amplifier and right one is called as non-inverting amplifier. This depends on where the input is being applied.

The gain of single ended to differential state is expressed as follows:
Vo/Vi = Rf/Rg
