An instrumentation amplifier can also be built with two op-amps to save on cost, but the gain must be higher than two (+6 dB). [ 4 ] [ 5 ] Instrumentation amplifiers can be built with individual op-amps and precision resistors, but are also available in integrated circuit from several manufacturers (including Texas Instruments , Analog Devices ...
The sensors which transimpedance amplifiers are used with usually have more capacitance than an op-amp can handle. The sensor can be modeled as a current source and a capacitor C i. [4] This capacitance across the input terminals of the op-amp, which includes the internal capacitance of the op-amp, introduces a low-pass filter in the feedback path.
It is a form of electronic amplifier with unity gain. There are three versions of generations of the idealised device, CCI, CCII and CCIII. [1] When configured with other circuit elements, real current conveyors can perform many analogue signal processing functions, in a similar manner to the way op-amps and the ideal concept of the op-amp are ...
ADI's companion amplifier ICs provide accurate, high-speed and precise signals for driving data converters and are key for applications such as digital audio, current sensing, and precision instrumentation. [50] The company's data converter chips are used by National Instruments in high-precision measurement instrumentation systems. [51]
An op-amp differential amplifier can be built with predictable and stable gain by applying negative feedback (Figure 5). [nb 5] Some kinds of differential amplifier usually include several simpler differential amplifiers. For example, a fully differential amplifier, an instrumentation amplifier, or an isolation amplifier are often built from a ...

[25] Widely used. LM747: Yes
where Z dif is the op-amp's input impedance to differential signals, and A OL is the open-loop voltage gain of the op-amp (which varies with frequency), and B is the feedback factor (the fraction of the output signal that returns to the input). [3] [4] In the case of the ideal op-amp, with A OL infinite and Z dif infinite, the input impedance ...
A log amplifier, which may spell log as logarithmic or logarithm and which may abbreviate amplifier as amp or be termed as a converter, is an electronic amplifier that for some range of input voltage has an output voltage approximately proportional to the logarithm of the input:
