Part Number: VCA822 Hi, I'm using VCA822 with cascade structure. Therefore, I could not give the right results of the simulations. With this structure below,
After U1, Instead of 1V, I get 724.8 mV as seen below.
After U2, I must get 2V if input…
Part Number: VCA822 I want to design programmable gain block with VCA822. The IC has 100V/V gain range but at simulation, the recommended resistor values for 100V/V (Rf = 845 ohm, Rg = 16.9 ohm) do not provide 100V/V at VG = 1V. The result has big offset…
Part Number: VCA822 Other Parts Discussed in Thread: TINA-TI Hello,
I'm using VCA822 into an AGC system in the configuration of Gmax = 10 (Rf = 1K, Rg =200) from a single-ended source.
VCA822 has quite big bandwidth (> 100MHz), and i need to filter…
Hi Betul,
The VCA822 has a very linear performance over its gain range.
As section 9.2 states, the VCA822 offers a typical gain accuracy of +/-0.1dB. Depending on varying conditions, that could range up to +/-0.3dB (such as operating temperature). Because…
Part Number: VCA822 Other Parts Discussed in Thread: VCA820 , , LMH6502 , LMH6503 Hi
On the datasheet, it is defined as the below.
And,
The maximum operating voltage is not defined. However, VCA820 it is defined as +/-6V on the datasheet,
Can we refer…
Part Number: VCA822 Hi,
I'm implementing a Voltage Controlled Amp using a VCA822. I have got two ICs, each time I connect and power them up to +/- 5V and GND the ICs over-heat to the point I am afraid they will be destroyed. There is no mention of…
Other Parts Discussed in Thread: VCA822 , OPA378 Hello,
I'm having trouble configuring the input of the VCA822, I am using it as a single ended input and feeding it from a OPA378 OpAmp. My problem is the signal coming out of the OPA378 was riding on a 2…
Part Number: LMH6505 Other Parts Discussed in Thread: VCA822 , VCA820 , VCA821 , VCA824 , LMH6714 , LMH6609 Hello, My customer would like to use LMH6505 as an AGC described in the figure 49 in the datasheet. However, they would like to use LMH6505 with V…
