Hi Tess,
Your 1.25MHz input may be filtered by the high-pass filter present in the LMH6515. The part has datasheet specs for 35MHz and I believe you mentioned it worked at your bandwidth of 25MHz. Could you confirm your load and bandwidth requirements…
Other Parts Discussed in Thread: LMH6515 , THS4304 I build up a schematic with LMH6515 as VGA shown below.
The opamp in this figure is THS4304. LMH6515 Pin13 is connectted to Pin16, so that its output impedance is 200ohm.
When I measured this design, I…
Here is my design: the differential input pins V+ is connected to previous stage's output; and V- is connected to a VCM=1.4V, which is a AC ground. In my application, the input of the VGA must be DC couple. Then there is a problem: the previous stages…
Other Parts Discussed in Thread: LMH6514 , LMH6515 Hi Team,
Can you please advise if we can offer alternative to CLC5526MSA.
Thanks in advance

Other Parts Discussed in Thread: LMH6515 Just want to make sure is the C11 (FIGURE on EV board datasheet). of LMH6515 evaluation board shorted on the PC board ? I check with m ultimeters, and it shows C11 is shorted, but not shorted in the datasheet.
Thank…
Hello Tess,
The LMH6521 doesn't seem to provide the parallel interface your are looking for?
In regards to the LMH6517, if you are willing to give up some game control from 0.5dB to 1dB for lower noise & increase minimum gain to -7dB then the LMH6515…
Other Parts Discussed in Thread: ADC16DV160 , LMH6554 , LMH6514 , LMH6515 HI
I am using LMH6554 to drive ADC16DV160 in AC coupled mode for the input signal of IF 60MHz, with -50dBm to 14dBm of Dynamic range.
I have biased LMH6554 with single supply 5V instead…
