Other Parts Discussed in Thread: LMH6502 , LMH6505 Hi All,
Could you please share the NF(Noise Figure) for LMH6502 and LMH6505? My customer wants to compare a NF based performance between TI and competitors.
Regards, Toshi
Hi Kawai-san,
You are correct that the LMH6502 model is not well-suited for single supply operation / simulation . I tried to setup a TINA-TI simulation file for the LMH6502 configured for single supply but I'm running into issues. Namely, even if I…
Hi Kawai-san, The 50ohm series output resistor is a desirable thing to have when probing the output as it isolates any cabling / connector parasitics and provides a 100ohm (=50+50) load (which is how the LMH6502 was characterized, mostly). Just factor…
Hello Hooman-san,
Thank you for your continuous help supporting LMH6502.
Does TI have any application note or documents of step response behavior ? It would be helpful for us if you could tell us the link where you could download the documents.…
Other Parts Discussed in Thread: LMH6502 , LMH730033 Hello,
Are there the EVM of LMH6502 TSSOP package ?
I can found the EVM of LMH6502 SOIC package only as LMH730033.
If there is the EVM of LMH6502 TSSOP package, please let me know.
Best…
Hello Takushi-san,
The LMH730033EVAL is apparently a 2 layer board. You could build the LMH6502 on a 4 layer board with layout stack up as: top layer - VS+ layer - VS- layer and Bottom layer. Another layout stack up could be a 6 layer board with: top…
Other Parts Discussed in Thread: LMH6505 , LMH6502 , LMH6518 Hello, Could you please let me know the competitive device with AD603? I already proposed LMH6505 and LMH6502. However, the customer request high gain accuracy in full temperature range. AD603…
Hi Koji-san,
The absolute maximum supply voltage for the VCA822 is provided in the datasheet on page 5 and should be +/-6.5V.
I believe the VCA822 is specified for operation from V+ = 7V to 12V and V- = GND. I don't think it can operated with V…
Hello George,
I did not see a filter on the block diagram. If there is a low pass filter it would still allow DC coupled operation. It appears that there is a voltage clamp in the block diagram. Figure 57 on Page 21 details the clamp circuit.
The…
Hi Erastus,
Please take a look at the LMH6503 Variable gain amplifier (minimum supply voltage 5V) with linear in V/V characteristics (similar to the VCA822). Figure 65, and Figure 66 show some possibilities with regard to using the part with a single…
