Part Number: OPA1611 Other Parts Discussed in Thread: LME49990 , OPA1612 Hi
With reference to this forum article , I also have a circuit wit the LME49990 in the circuit that I replaced with OPA1611. Simulation is showing great results. I would like…
Part Number: TLV3501 Hi,
I intend to use TLV3501 to build a zero crossing comparator and use OPA1611 to build a integrator.
The input voltage vg is a +/- 1V 100kHz sine wave. The desired working waveforms is： TLV3501 output a +/-2.5V 100kHz squre…
Part Number: OPA1611 Other Parts Discussed in Thread: TINA-TI Dear E2E support,
I am trying to simulate the effect of stray capacitances due to metallic enclosure to an amplifier circuit, according to the model proposed by Ott in his book "Noise reduction…
Part Number: OPA1611 Other Parts Discussed in Thread: PCM1792 , PCM1794A , OPA1637 , THS4561 , THS4131 , OPA1632 , OPA1692 I was looking at the example ckt in the OPA1611 datasheet (figure 35), and this, like several others, show the diff to single stage…
Trent,
OPA1611 typically draws around 3.6mA of the quiescent current so it is reasonable to see just 3mA. However, I am not sure what you mean by 'no output voltage or current is produced' - there is always some potential at the output while the output…
Thanks! I thought of this way, but I thought it was rather inaccurate. I knew it was hard to acquire the actual poles and zero's if you don't have the actualy schematic. After all it's the whole reason I started wondering how I could do it even at all…
Hi Jones ,
L1 and C1 is there to "break the loop" for loop-gain simulation.
1Terahenry and 1Terafarad may not exist in the world. But here is what it does during simulation. 1Th in L1 is to maintain the DC feedback or bias to your your feedback loop…
Hi Kato,
The model for the OPA1611 does model open loop gain and phase and output impedance of the OPA1611.
In your design, the phase shift at Vout does not represent the phase margin of the circuit. You should instead measure the phase where feedback…
Part Number: OPA1611 Other Parts Discussed in Thread: OPA1612 , OPA1622 We have a question for the OPA1611 amplifeir: and the graph of Figure 7. THD+N Ratio vs Frequency. It shows that amplifier distortions are higher for the load resistance of 600 Ohm…
