Part Number: VCA810
Hello Experts,
I want to design a variable gain voltage amplifier for lower cut-off frequency around ~500 Hz (upper limit doesn't matter) and gain of ~900V/V.
I am getting a DC offset which I don't want, and is this design practically…
Hi Harshini,
For AGC applications, the control voltage will change in relation to the input signal of the AGC circuitry. The waveforms will look something like this:
The attack time and decay time determine how fast the AGC circuitry responds with a variable…
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…
Part Number: VCA810 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models How to adjust the bandwidth using VCA810 or a filter?
Part Number: VCA810 Hello, I have an application where I need to use a VGA but I also need to get a monotonic step response. With "monotonic" I mean that I need first-order responses and avoid overshoots, especially for the falling edge of the input signal…
Part Number: VCA810 Hello,
Can we use VCA810 as single-end and AC-cuppled input as below?
This circuit will be used in Audio equipment for Volume control. Would you please advise me how ot use in Audio equipment.

Part Number: VCA810 Hi
There is the characteristics graph of frequency and gain on the datasheet.
What does this graph mean? Is DC(=low frequency) input acceptable?
Our customer measured the output voltage with DC input (+IN=-0.5V and -IN=GND). However…
Part Number: VCA810 Other Parts Discussed in Thread: TINA-TI Hello,
Our customer evaluating VCA810 with input voltage= -1V to +1V and gain=0dB, however, the output voltage has clamped.
I have heard their operation conditions and settings and examined…
Part Number: VCA810 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi all Would you mind if we ask TINA-TI simulation with VCA810? Please refer to following file. 2656.20170808_VCA810_circuit.TSC On this file, we would like…
Part Number: VCA810 Hi Team,
The customer needs to get the differences between VCA810AID and VCA810ID. Can you support this?
