Other Parts Discussed in Thread: VCA810 I was so confuced about the ocsillation of VCA810,i read the datasheet again and again,but i could not find the solution.
i used followed schematic ,but i adjusted the gain control vc above -1.2(about 8 dB),the…
Part Number: THS7530 Other Parts Discussed in Thread: VCA810 , VCA2612 , LMH6401 , VCA820 Hello,
I'm looking about the THS7530 to make a high gain fully diifferential amplifier. Regarding the datasheet, I see that THS7530 used a modified Gilbert cell structure…
Other Parts Discussed in Thread: VCA810 , VCA822 , VCA824 I am using the VCA810 for a gain control circuit. I have it in an AGC loop and it works well. As another option from my multipurpose board, I wish to drive the control input directly from a DAC and…
Hello Rock,
We have app notes and reference circuits with a RC based oscillator with an AGC such as these links: link1 and link2 . There is also a simpler AGC reference circuit in the VCA810 's datasheet which is Figure 36 and 38.
Thank you,
Sima
Other Parts Discussed in Thread: VCA810 , DAC8532 Hello:
I am working with the VCA810 and have subjected it to a -2.9V control voltage, I have read in the application notes that voltages below -2.5V should be avoided to prevent saturation. Is it possible…
Hi, Polly,
I could only find this voltage-controlled amplifier:

In addition, there are some audio amplifiers that have volume control through DC level, please see the suggested devices below:

Well just responding tothe AGC part,
the dB/V gain control versions are what you want if you are building your own AGC - the VCA820 describes this but is likely too fast for what you need. You might also look at the VCA810 for a slower design point
There…
