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?
