Exempel på hur man kan använda OP-AMP i en mening

• Although the instrumentation amplifier is usually shown schematically identical to a standard operational amplifier (op-amp), the electronic instrumentation amplifier is almost always internally composed of 3 op-amps.
• The op-amps inputs feature 2-to-1 analog multiplexer, allowing for a total of eight analog channels to be pre-processed using the op-amp; all the op-amp outputs can be internally connected to ADCs.
• This circuit is of limited use in applications relying on the back EMF property of an inductor, as this effect will be limited in a gyrator circuit to the voltage supplies of the op-amp.
• After the 1960s, analog synthesizers were built using operational amplifier (op-amp) integrated circuits, and used potentiometers (pots, or variable resistors) to adjust the sound parameters.
• Luna Overdrive, containing a Baxandall tone circuit, an op-amp, and a JFET circuit "voiced like a Fender or Marshall preamplifier circuit".
• Some less usual peripheral options include on-chip operational amplifiers (op-amp) for signal conditioning, 12-bit digital-to-analog converter (DAC), liquid crystal display (LCD) driver, hardware multiplier, USB, and direct memory access (DMA) for ADC results.
• The transimpedance amplifier and an op-amp inverting amplifier are typical implementations of this idea.
• High-power devices (such as high-voltage op-amp ICs, voltage regulators, and motor driver ICs) are still being manufactured in a package with a zig-zag pinout (and normally screwed onto a heatsink).
• A more sophisticated use of this rail bootstrapping technique is to alter the non-linear C/V characteristic of the inputs of a JFET op-amp in order to decrease its distortion.
• The quadrature oscillator uses two cascaded op-amp integrators in a feedback loop, one with the signal applied to the inverting input or two integrators and an invertor.
• Many voltage-controlled oscillators for electronic music are based on a capacitor charging linearly in an op-amp integrator configuration.
