运算放大器(op-amp)是放大两个输入之间电压差的集成电路(IC) 由于它是为执行算术运算而开发的,所以如此命名。放大器、缓冲器、比较器、滤波器等可以用简单的外部电路来实现。 运算放大器有五个端子:正电源、负电源(GND)、同相输入、反相输入和输出。通常,这些端子的命名如下所示。(单电源运算放大器的...

The buffer amps buffer the output transistors' gate capacitances, thereby allowing the output transistors to be nearly any desired size without adversely affecting the op amp's dynamic performance. This enables the op amp's compensation capacitors to set the amplifier's bandwidth, and allows the ...
Non-inverting amplifier In this case, the output voltage is always in phase with the input voltage, which is why this topology is known as non-inverting. Voltage follower (unity buffer amplifier) This circuit does not generally require external components, and provides high input impedance and lo...
parts of a system without potentially disturbing or altering the voltage. Often a buffer amplifier is required or the voltage may need to be shifter or “referred” to a different node (supply voltage or ground) in the circuit. Op amp circuits like those in figure 4.2 can perform this ...
An amplifier is a circuit which can produce an output voltage, which is the product of input voltage with a value called voltage gain. An op-amp (operational amplifier) is a kind of amplifier circuit which can perform an operation (addition, subtraction etc.) on the input voltages, apart ...

The first stage in the data acquisition electronics signal path can often be an op amp configured as a buffer or a gain amplifier. The input to that op amp is exposed to the outside world and therefore can be subjected to overvoltage incidents, like a short circuit from a damaged cable ...
This page on op-amp cover Operational Amplifier basics, its use as inverting, non inverting, summing amplifier, voltage comparator and more. op-amp stands for Operational Amplifier. Earlier op-amps were made using discrete components. They were used in analog computers for various functions such ...
