Part Number: VCA820 Other Parts Discussed in Thread: OPA695 , OPA820 , Hello Kai,
I working for AGC network which works for 30ns to 200ns for that purpose I have implemented VCA820 circuit with OPA695 and OPA820 for feedback integrator, but I couldn't simulate…
Part Number: VCA820 Hi team,
I want to use this device as below, Rf=845Ohm, Rg=16.9, Vg=2V, which means Avmax=40dB;
When I apply VG1 signal, Vpp=5mV, f=20MHz, we can see that Vpp of VF1 is about 700mV. This is not aligned with the gain*Vpp=500mV. What…
Part Number: VCA820 I am looking for a VGA 10MHz , with -10 to +10 db gain operating with a single supply and single ended. Can VCA820 b e used with single power supply 10VDC? or can you suggest an alternative part number
Part Number: THS4520 Other Parts Discussed in Thread: THS4541 , THS3215 , VCA820 Hi,
To replace AD8130, I am thinking of THS4520 or THS4541 in terms of frequency. Can these ICs do differential to single end conversion?
Also, please let me know if there…
Part Number: VCA821 Other Parts Discussed in Thread: OPA820 , VCA820 , TINA-TI , OPA856
Hello Team, I am working with Automatic Gain controller on a high BW of 30MHz communication line.
For this application I have choose VCA821 VGA and OPA820 comparator…
Other Parts Discussed in Thread: VCA820 , TINA-TI Dear all
My customer is evaluating VCA820, they will provide a high frequency voltage(around 30MHz or even higher) to VCA820, so they want to know how long it will take for the VCA820 to change its gain…
Part Number: VCA824 Other Parts Discussed in Thread: VCA820 Hi Team,
Does this part have any ACG (automatic gain control) reference circuit for MIC application? Thanks.
Best Regards,
Tess Chen
Hello Amy,
I have not forgotten about getting a good explanation to you; I am working with my manager to best understand how to communicate the selection of AGC parameters.
While I am working on this, please see this thread for more information: https…
Hello Hirano-San,
The input signal into the LMH6505 would be within range; however, there might be an issue into the following stages (within the AGC loop control) due to the DC offset cancellation. I am looking into this a bit more.
Also, we have other…
Other Parts Discussed in Thread: VCA821 , VCA820 , VCA822 , VCA824 Hallo,
I have a question. What are VCTRL0 and VSLOPE in the VCA820 / VCA821 datasheet and Figure7 of the VCA821 datasheet? The VCA822 / VCA824 have not these specs. Are these specs for the gain…
