The LT1013 is a precision JFET-input operational amplifier, and its equivalent can be considered the TL071, which also features a JFET input. The LMC662, a dual op-amp with low power consumption, can be compared to the LM358, although the LM358 is not a low-power op-amp. For precise applications, the OPA2134 may also serve as a modern equivalent to either due to its high performance and low distortion characteristics.
What else can I help you with?
What happens when magnitude of Vcc and Vee of op-amp are different?
When the magnitude of Vcc and Vee of op-amp are different the op-amp produces waveforms equal in the size of each rail.
How can an op amp comparator circuit be used for converting sine to square wave?
The wording are confusing an op-amp is an op-amp a comparator is another animal. an op-amp can be used as square wave generator by overdriving it but the results are not desirable. However a comparator will be a switch on-off at the set level.
What are the ideal op-amp approximations?
Ideal op amp approximations: -no current goes into the positive or negative input of the op amp. -The open loop gain is infinite. -Voltage at positive input is the same as the negative input.
How gain varies with bandwidth in an op-amp?
The gain of an op amp varies with frequency. After an op amp reaches the half-power point, the gain falls appreciably. And then once it hits the transition frequency, the op amp no longer provides any gain.
How do you use OP-AMP as common compensator?
i know that an op amp can be used as an amplifier and a switch, but i want to have more uses of the component or device.
What the concept of op-amp output current?
A: An op amp will have the capability to drive a load equivalent to its maximum output if more current is tried to for out the last stage will saturate causing malfunction of the circuit but if not sustained for too long it need not be catastrophic reducing the load can restore the op amp because of its protective design.
What happens when magnitude of Vcc and Vee of op-amp are different?
When the magnitude of Vcc and Vee of op-amp are different the op-amp produces waveforms equal in the size of each rail.
How an op amp differs from a basic amp?
A basic, single transistor amplifier differs from an op amp: 1. The op amp has more gain 2. The op amp may have higher input resistance (so it loads the circuit less) 3. The op amp may have a lower output resistance (so it can drive larger currents) 4. The op amp likely has a lower frequency response (due to the high gain, unless you provide some sort of feedback loop) 5. The op amp is ridiculously complex compared to a simple amplifier 6. The op amp will require a positive and negative voltage (may be unnecessary with a single transistor amplifier)
Which characteristics of Op-Amp is responsible for virtual ground?
The main parameter responsible for virtual ground of an Op-Amp is Input Impedance . Generally , for an Op-Amp it is very high . So , we can conclude that the characteristics of an Op-Amp responsible for virtual ground is high input impedance .
Why feedback is used in op-amp?
Feedback in used in an op-amp to limit and control the gain. An op-amp, by itself, has very high gain, often more than 100,000. (A theoretical op-amp has infinite gain.) The external feedback loop forms a divider, more correctly a bridge, that is maintained in balance by the op-amp, giving the desired real gain.
What is LM312T?
op-amp
How can an OP-AMP be nulled?
op-amp can be nulled using offset voltage about +/- 1.5 mv to offset pins
What is use of 8th pin in op-amp?
This may vary from one op-amp to another, consult the datasheet.
