Other Parts Discussed in Thread: VCA810 Hello, I used VCA810 in projectsach as regulator of power level of RF. But sometching is incorect. My RF link contain : DDS(source) -> direfential-to-singe operational amp -> low pass filter -> VCA810(end). But when…
Hello Hirano-San,
The input signal into the LMH6505 would be within range; however, there might be an issue into the following stages (within the AGC loop control) due to the DC offset cancellation. I am looking into this a bit more.
Also, we have other…
Other Parts Discussed in Thread: VCA810 , VCA822 , LMH6505 , VCA820 , VCA821 , PGA281 , PGA280 Hello,
I'm looking for help in designing an Automatic Gain Control Circuit for slow random wave forms ranging from 0.1Hz to 100Hz. The input signals vary from 50mVpk…
Other Parts Discussed in Thread: VCA810 , VCA820 Hi there,
trying to implement the VCA810 in a customer application we found some odd things.
- Page 3: voltage output swing contains two entries with the same text “Vc = -2V, RL = 100Ohm” ->…
Part Number: ADS1261 Other Parts Discussed in Thread: VCA810 , INA849 , ADS125H02 Hi,
I need to measure a variable resistance over a wide range, the top of the range being 2Mega ohms. The intention is to reap all the benefits of differential measurement…
Other Parts Discussed in Thread: VCA810 I've been prototyping using this VCA for a compressor - for audio purposes. The VCA is controlled by the PWM output of an mcu. The (filtered of course) PWM output sits on -1V until told to boost or cut by the mcu…
Other Parts Discussed in Thread: LMH6505 Is there an app note or cookbook of a VCA 810 dc coupled non inverting AGC amp or compressor?
The signal is a few hundred Hz. The application is ion sense combustion monitoring.
Ok, your 100kHz is pretty low for this function, but here is a possible solution
The VCA810 has the range but needs a post FDA to go back to differential out with fixed gain of 20dB - I used the THS4561 a +/-5V capable very low power FDA.
The VCA810 was…
Other Parts Discussed in Thread: VCA810 Hi evry one
Please help me.
I would like to use the vca810 , to keep the sound pressure level constant on the micrphone . The problem is that I have to use a +5V single supply , and I do not see on the datasheet o…
Part Number: TL026 Other Parts Discussed in Thread: LMH6505 , THS7530 , VCA810 I'm looking for an AGC amplifier replacement for the venerable MC1350 and are looking at the TL026 but it doesn't seem to be applicable as a replacement. Have I missed something…
