WebApr 11, 2024 · The op-amp differential amplifier features low output resistance, high input resistance, and high open loop gain. In an inverting amplifier configuration, the op-amp circuit output gain is negative. All simple mathematical operations such as addition, subtraction, comparison, etc. are possible with op-amp application circuits. WebElectrical Amplifier Gains: Voltage, Current, and/or Power. Electrical amplifier gains may be expressed in terms of voltage, current, and/or power in both AC and DC. A summary of gain definitions is as follows: The triangle-shaped “delta” symbol (Δ) represents change in mathematics, so “ΔV output / ΔV input ” means “change in ...
