Noun
op-amp (plural op-amps)
(electronics) A certain active circuit element useful in creating various kinds of amplifiers and filters.
A differential amplifier is the first stage of an op-amp, a differential amplifier consists of two transistors which are emitter coupled. Source: Internet
A single sided supply op-amp is one where the input and output voltages can be as low as the negative power supply voltage instead of needing to be at least two volts above it. Source: Internet
A real op-amp may be modeled with non-infinite or non-zero parameters using equivalent resistors and capacitors in the op-amp model. Source: Internet
As an example, the LT1494 micropower op-amp consumes 1.5 microamp but has a 2.7 kHz gain-bandwidth product and a 0.001 V per microsecond slew rate. Source: Internet
Closed loop An op-amp with negative feedback (a non-inverting amplifier) If predictable operation is desired, negative feedback is used, by applying a portion of the output voltage to the inverting input. Source: Internet
;Drift: Real op-amp parameters are subject to slow change over time and with changes in temperature, input conditions, etc. AC imperfections The op-amp gain calculated at DC does not apply at higher frequencies. Source: Internet
