WHERE TO USE AD8675ARMZ-REEL?
AD8675ARMZ-REEL is an op-amp which can be used as an operational amplifier (In linear region) or as a switch (In non-linear region). AD8675ARMZ-REEL as an operational amplifier can be used to amplify any measured small signals or difference between two signals. It can also be used to develop voltage to current/current to voltage converter. It can be utilized to develop integrator or differentiator circuits which are useful in control of electrical devices.
How AD8675ARMZ-REEL work?
 Figure 3 Circuit Diagram of AD8675ARMZ |
Fig.3 shows circuit diagram of AD8675ARMZ as a non-inverting operational amplifier. In this configuration, the input voltage signal, (VIN) is applied directly to the non-inverting (+) input terminal which means that the output gain of the amplifier becomes Positive. Closed loop voltage gain of a Non-inverting Operational Amplifier will be given as: . Output voltage is amplified by the voltage gain Av and can be calculated as
