Part Number: LMH6505 Dear support,
I am looking for a variable gain amplifier.
When the input is very high the gain is less, when the input is small, the gain is big.
And the output to be a constant.
Will you be able to recommend to any VGA that can work…
Part Number: LMH6505 Hi, I'm using this component as a VGA (gain driven by a DAC) and I'm not seeing anything on the output. I'm wondering if I've possibly damaged it.
Configuration: typical application with Rin=10K, Rg=374, Rf=3.74K.…
Part Number: LMH6505 I am working on evaluating the LMH6505 (currently on eval board) as a replacement for the ML1350. I had a quick technical question regarding if the LMH6505 has the possibility of inverting the Gain Control voltage scale. Such as in…
Part Number: LMH6505 Hi, the LMH6505 in our system runs off of +/5V and has its Vg pin driven by an op amp stage that can swing to the +/-12V rails. There is a 2.7k resistor in series between the op amp and the Vg pin. Fairly often the output of the op…
Part Number: LMH6505 Hi
The datasheet of LMH6505 explains that RG determines the input voltage range. I struggle to understand how a resistor which is connected to the output of buffer sets the input voltage range. Can you explain it in further detail? …
Part Number: LMH6505 Hello,
I am powering an LMH6505 with two LDOs, one which regulates 6V to 5V, and one which regulates -6.5V to -5V. The part is upstream of a differential amplifier that is powered by the same rails. Currently, our power rails are…
Part Number: LMH6505 Other Parts Discussed in Thread: LMH6504 The LMH6505 datasheet specifies an output impedance at DC (0.12 ohms) and the section on transmission line matching specifies that this output impedance increases with frequency, but there…
Part Number: LMH6505 The circuit is built according to the typical circuit of lmh6505 datsheet. The positive and negative 5V system supplies power, and the 1kHz 0.7V sine wave signal is input. The control voltage signal VG changes from 0-1v, and the maximum…
Part Number: LMH6505 Other Parts Discussed in Thread: THS4131 , VCA820 Hi,
We are using LMH6505 & THS4131(using these 2 chips for differential function, just use their noise data for analysis, not compare apple and apple)。
Seems that we found the LMH6505…
