Hello José,
Thank you so much for your patience. I was looking over this device in depth, and this device does have varying output voltages depending on gain setting.
Comparing to your table, Figure 1, from your testing it doesn't really follow…
Part Number: VCA810 Other Parts Discussed in Thread: VCA822 , LMH6503 , LMH6505 , VCA821 Hi, I'm using VCA810. The deviations of positive and negative cycles of the input signal are high. For ex: 1. Gain = 55.4865 (with external resistor block and VCA810…
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…
Part Number: VCA810 Hello,
when simulating the circuit shown in datasheet fig. 36 and connecting the input voltage of 10 mV via a series resistor I get a significant input signal attenuation.
The datasheet states an input impedance of 1 Meg but calculations…
Part Number: VCA810 Other Parts Discussed in Thread: VCA820 , TINA-TI Hello,
I am trying to design a AGC circuit based on the VCA810. using the circuit shown in figure 36 of the datasheet, I was able to replicate the circuit in PSpice and simulate it…
Part Number: VCA810
I want to design a variable gain voltage amplifier of bandwidth 100kHz (i.e ~500Hz to ~95kHz) and gain ~900V/V using VCA810.
What should be my Vc 1 and Vc 2?
Is this design practically correct?
