Other Parts Discussed in Thread: VCA822 , LMH6505 , VCA820 , OPA820 What happens with the VCA820 or VCA822 if the Gain Control (Vg) voltage falls out of the normal operating range of 0V to 2V (For VCA820) and -1V to 1V (For VCA822)? The LMH6505 warns against…
Part Number: LMH6503 Other Parts Discussed in Thread: VCA822 , VCA820 , VCA824 Hello, on page 19 of LMH6503 daatasheet, Figure 61 shows how to adjust (on pin 12) the output offset of the LMH6503 IC. Can this adjustment be useful to adjust the offset from…
Part Number: LMH6505 Other Parts Discussed in Thread: VCA820 , VCA822 , VCA821 , VCA824 Hi,
We are using the LMH6505, its gain will change with the temperature. I want to ask
-The left gain coefficient of temperature, do we can use right gain forum to calcualte…
I need to replace a LMH6530 with a linear/linear device so it still looks like the VCA824 is the best option. The VCA822 has limited bandwidth of only 150M. I need to be able to process signals at 180MHz and have a VGA function.
Part Number: VCA810 Other Parts Discussed in Thread: VCA822 Dear all,
I need to control the amplitude of a sinusoidal signal with frequency between 0 and 1 kHz and amplitude 1V. I am guessing to use the VCA810 with a voltage analog input 0 - 5V.
1) Can…
thank you for the reply Samir.
follow up question.
If i'll be needing a total gain of 200-500,
1. Would cascading VCA822s or VCA821s have a better overall performance?
2. How do i configure the gain for LMH3401?
3. What are the possible gains for…
Samir,you mentioned that the opa847 is unstable below gain of 12V/V.
1. Where is that written in the datasheet?
2. Can i operate vca821 or vca822 in unity gain? I plan to use it as a clamping ckt.

I'm looking for help in designing an Automatic Gain Control Circuit for slow random wave forms ranging from 0.1Hz to 100Hz. The input signals vary from 50mVpk…
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…
