Part Number: VCA810 Tool/software: Hello, I have a question concerning the VCA810 Wideband and Variable Gain Amplifier that I use as a Log Amplifier from -40dB to 40dB gain.
According to the datasheet, the component has an VOLTAGE_OUTPUT_SWING = +/…
Part Number: VCA810 Tool/software: Are there app notes or reccomended circuits for using an ampifier like the VCA810 to apply a linear or logoroithmic TVG for a ~40khz signal (or higher freq) across temperature without having to wake up an MCU? Or, is…
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…
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…
Part Number: VCA810 Other Parts Discussed in Thread: VCA820 Hi team,
After looking at the thread of the related question, I still don't understand how to set the parameters in the circuit. If the input signal is 500KHZ, how should the parameters be…
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…
Hi,
The VCA810 has a max gain of 40dB (100 V/V) when the VC pin is set at -2V. Since you only need 900 V/V and can get 100V/V from the VCA810, I would actually suggest you just follow the first stage with a gain of 9 V/V amplifier instead of using…
Part Number: VCA810 Other Parts Discussed in Thread: ADC3424 , VCA820 , LMH6609 , VCA821 Hi team,
My customer is using VCA810 to control the sine waveform amplitude, see schematic below, but they find that our device will cause a non-linear issue to…
