Part Number: OPA860 I do not quite understand the Control-Loop Amplifier Using Two OPA860s as shown in Fig 55 of the data sheet. Can someone please explain that with a real life example and values? Thanks.
Hi,
It's the nature of bandpass filter especially LC tank. LC tank has a high Q resonant where it has high peak and smaller bandwidth around that peak that can maintain about the same gain. This is why when you try to sweep it across frequency, the…
Other Parts Discussed in Thread: OPA860 , TINA-TI , OPA615 , LMV7219 I just searched for a voltage controlled current source IC, with wide bandwidth above 50MHz, high adjustable trans-conductance and wide linear range. By comparison, I think OPA860 maybe…
Other Parts Discussed in Thread: OPA860 , OPA861 HI every one, I am using OPA 860 IC for VCCS, but i think my circuit is incorrect. Any one will give single supply based VCCS using OPA860 circuit.
Other Parts Discussed in Thread: OPA860 Hi, iam using OPA860 in a application and i giving 3.3v positive supply and i short negative supply to ground and i using this ic for VCCS along with some other circuit. my question: is this device only work for…
Other Parts Discussed in Thread: OPA860 Hello E2E Team,
I have a customer that is trying to implement and simulate the OPA860. They are currently using the device as a current source to test a trans-impedance amplifier(TIA) circuit.
The setup is simply…
Other Parts Discussed in Thread: OPA860 I have a DC (Audio type) Power Amplifier, on +/- 40-volt rails, in which I want to "Current-Sense" the output (for instrumentation - not protection). Typically this is done with a high value input resistor Instrumentation…
Other Parts Discussed in Thread: OPA861 , TINA-TI I'm looking at figure 11 in this document:

This is kind of a dumb question but how do I select Rcomp and Ccomp for the propagation delay? Since I want…
Part Number: OPA1S2384 Other Parts Discussed in Thread: OPA615 , OPA860 , OPA1S2385 Tool/software: Hi team,
The customers want to select an op-amp and the requirement is as below:
Differential signal to single-ended signal 3.3V supply, input signal…
Hello Chen,
Thank you for reaching out and for the application summary.
For the block diagram, do you mean the OPA847 is used as your TIA/pre-amp stage followed by OPA861 as the OTA (peak detector + hold) then LMH6601 as the buffer amplifier?
