differential input in a sentence

"' Negative impedance with voltage inversion "'is implemented by applying both negative and positive feedback to an op-amp amplifier with a differential input.
The differential input made a whole range of new functionality possible, but it would not be used for a long time due to the rise of the chopper-stabilized amplifier.
The output of the parallel voltage summer is single-ended ( it produces voltage with respect to ground ) so the circuit does not need an amplifier with a differential input.
In instrumentation systems, the use of differential inputs with high common mode rejection ratio, to minimise the effects of induced AC signals on the parameter to be measured, is widespread.
To save pins, it is common for slow ADCs to send their data one bit at a time over a differential inputs, where the quantity measured is the difference between two voltages.

Hewlett's Wien bridge oscillator can be considered as a combination of a differential amplifier and a Wien bridge, connected in a positive feedback loop between the amplifier output and differential inputs.
The "'LM13700 "'is an integrated circuit consisting of two current controlled operational transconductance amplifiers ( OTA ), each having differential inputs and a push-pull output.
The op-amp non-inverting amplifier is a typical circuit with series negative feedback based on the Miller theorem, where the op-amp differential input impedance is apparently increased up to infinity
The op-amp inverting amplifier is a typical circuit, with parallel negative feedback, based on the Miller theorem, where the op-amp differential input impedance is apparently decreased up to zero
In this case, the differential input signal across the input terminals IN + and IN " is multiplied by the circuit gain to generate a differential output signal across OUT + and OUT " terminals.
