Anop-ampis implemented to simply convert the voltage signal to corresponding current signal. The Op-amp used for this purpose is IC LM741. This Op-amp is designed to hold the precise amount of current by applying the voltage which is essential to sustain thatcurrentthrough out the circuit. ...
sir, i have a 0-10 V Dc supply with 600 ohm impedance. i want a current from 30ma to 1 A as we change voltage from 0 to 10V across 50 ohm resistor. kindly inform me about the circuit and which op amp i have to use for t Your needs are not entirely clear but I suggest th...
directly from transducer devices, whereas accurate current signals are not. Op-amps can be used to “convert” a voltage signal into a current signal quite easily. In this mode, the op-amp will output whatever voltage is necessary to maintain current through the signaling circuit at the proper...
Every op-amp has an internal DC error voltage, known as the input offset voltage, VOS, which causes it to output a voltage even if its inputs are zero. the DC voltage that must be applied between the input terminals to force the quiescent DC output voltage to zero or some other level,...
Owing to its long history, the VFA comes in many varieties and packages, so VFAs are applicable to almost any job. VFA bandwidth is limited, so it cannot function well at high signal frequencies as the CFA can. The signal frequency and precision separates the applications of the two op ...
For low-impedance loads, the use of a high-voltage op amp with a high-current-drive output simplifies the circuit design by eliminating the need for external power FETs.Maurizio GavardoniProduct Definer
A new transformation method is presented and used to transform voltage-mode op-amp-RC circuits to current-mode Gm-C ones. The proposed method enables the generation of high-performance Gm-C filters that benefit from the advantages of good and well-known op-amp-RC structures and the advantages...
ST's high-voltage op-amps (10 V to 36 V) offer many combinations of power consumption and gain bandwidth, allowing you to get the best performance for the appropriate accuracy.
If an op amp has protection diodes it will typically have a spec for maximum differential input current. The protection circuit should also show up on the simplified schematic. Some op amps also have back-to-back diodes across the inputs. These are not for input over- voltage protection, ...
Note that in this single supply circuit the output cannot truly swing all the way to 0V. How close it can swing to zero will depend on the op amp load current. Please begin posting any future unrelated questions in a separate posting. This thread now has several unrelated circuit topics ...
