What analysis are you running there? You just want to get the DC setpoints, right? And the results for the ideal opamp look wrong -- how can -1nA through the 10M resistor and the 10:1 divider give you something * 10^-30? The result for the TL070 opamp looks more reasonable...gazp1988 said:
Ah, sorry, I got them backwards. There must be some hookup problem with the TL072 schematic. Why are there blue X's on the input & output connections for the ideal opamp schematic, but not on the TL072 version?gazp1988 said:
I only see the output node probe. What about all of the other nodes?gazp1988 said:
Can you probe the power supply terminals of the opamp? I still think they are not connected...gazp1988 said:
No way. The power supply rails for an opamp need to be in the +/-12V range. Not 10mV. Set them to +/-12V for both simulations and see what happens.gazp1988 said:
So what are you going to set as your power supply values now? Do both simulations work now with +/-12V rails?gazp1988 said:
The TL 072 is a type of operational amplifier (op-amp) that is commonly used in electronic circuits. It is a high-gain, direct-coupled amplifier that amplifies the difference voltage between its two input terminals. It works by using a differential amplifier configuration to amplify small input signals to a larger output signal.
There are several factors that can affect the output of a TL 072 op-amp, including the input voltage, supply voltage, temperature, and external components such as resistors and capacitors. These factors can influence the gain, bandwidth, and stability of the op-amp, which in turn affects the output signal.
The input voltage is a crucial factor in determining the output of a TL 072 op-amp. As the input voltage increases, the output voltage will also increase, but it is important to note that the op-amp has a limited output voltage range. If the input voltage exceeds this range, the output will saturate and no longer accurately reflect the input signal.
Yes, the supply voltage can have a significant impact on the output of a TL 072 op-amp. The op-amp requires a stable supply voltage to function properly, and any fluctuations or noise in the supply voltage can cause distortion in the output signal. It is important to ensure that the supply voltage is within the recommended range for the op-amp to ensure optimal performance.
External components such as resistors and capacitors can affect the output of a TL 072 op-amp in several ways. These components are often used to adjust the gain or frequency response of the op-amp, and if they are not chosen or connected correctly, they can cause distortion or instability in the output signal. It is important to carefully select and properly connect these external components to ensure the desired output is achieved.
