The sketch below shows a single op-amp configured as a variable gain differential amplifier that uses only one variable resistance as a gain adjustment and which maintains, if not a superb value, at ...

Standard circuits such as an inverting amplifier are your bread and butter, and the formula gain ... circuit op-amps will incorporate one in some form or another. It is a differential amplifier ...

One of my previous columns explains a method for calculating decreasing open-loop-gain-induced errors (Reference 1). Several readers requested a simpler error-function explanation, so this one uses op ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having ...

b. The gain is set by VCC as the higher the supply voltage, the higher the gain. c. By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the ...

The circuit shown is a differential amplifier that not only offers programmability but also provides a logarithmic-type gain (Fig. 1). The traditional gain-setting resistors of the amplifier ...

Called CFBplus, these op amps unshackle the gain from the bandwidth ... This is particularly useful in the differential driver or receiver stages to equalize the high-frequency attenuation ...

Texas Instruments has introduced its first differential amplifiers which are programmable for variable gain. The 2.4GHz LMH6881 single-channel and 2.4GHz LMH6882 dual-channel amplifiers have a 6dB to ...

Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC6432-15, a wideband fully differential amplifier with 15dB gain, offering linearity of up to +50.3dBm OIP3 ...

Analog Devices has created a fast power op-amp that can handle ±55V rails and ±1A ... to be configured with high gain for low input voltages, or low gain for high input voltages. All negative-feedback ...
