Part Number: OPA1611 Dear Sirs,
We use OPA1611AIDR and OPA1612AIDR chips and have two technical questions related to them: Is it possible to tell from the markings where they are manufactured? (location) Are there differences in the manufacturing process…
Part Number: OPA1611 Tool/software: Where can I find a downloadable spice model of OPA1611/12 for simulation? I'm unable to find it on the product page. I used to be able to download models easily, now your website makes it impossible...why is this so…
Part Number: OPA1611 Hi,
I am we got one circuit for Wien bridge Oscillator. Trying to evaluate. Created file in TINA, but not able to see 500KHz o/p.
What could be purpose of RC series switched through FET. FET is applied with 500KHz pules of 0…
Part Number: OPA1611 Dear Support,
the OPA1611 datasheet says that GBW is 80 MHz @ Gain =100 and is equal to 40 MHz @ Gain = 1. Could you please explain me such a strange behavior ? Is data in the datasheet correct ?
Does GBW = 80 MHz @ Gain =100…
Part Number: OPA1611 Other Parts Discussed in Thread: OPA856 Hi Team,
A customer is looking for an alternative for OPA1611 with an open-loop gain greater than 20dB or as high as it comes at 20MHz. with low noise of 1nV/RT-HZ or up to 2nV/RT-HZ.
…
Hi Cato,
Question:
The output of OPA1611 has a obvious DC offset. What confuses me is that how this DC offset occurs and how to avoid it.
Can you explain what how your DC offset is referenced to? I don't think that you are talking about Vos value…
Part Number: OPA1611 Other Parts Discussed in Thread: TINA-TI , , OPA828 Hi,
I'm planning an ultra low noise & Distortion Speakeramp. I want to reach the voltage (+-50V) to feed the Voltage follower Transistor Out-Stage by Bootstrapping the Powersupply…
Hi Iwata-san,
Thank you for the explanation.
As you mentioned, the topology of each output stage seems to be different as follows.
I understand.
Best regards, Kato
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…
