Part Number: LMH6514
Tool/software:
Hello,
I'm looking for help understanding the capabilities of this amplifier.
If I understand correctly, this part first amplifies a signal (gain determined by the internal + external load), then attenuates…
Part Number: LMH6514 Hello team,
I couldn't find SPICE model of DVGA LMH6514 in TI website. Do you have any SPICE model of this part or any part having similar analog performance?
Thank you in advance

Other Parts Discussed in Thread: LMH6514 Dear，
I used LMH6514 for design, but there is no any output . The Power supply is normal, and Gain0~2 & Latch used with 3.3V logic signal. I try Gain0~2 for 000,001,010 ect but all are the same, no any output…
Part Number: LMH6514 Other Parts Discussed in Thread: THS4551 , THS7530 , LMH6518 , LMH6629 Hi team,
A customer reviews LMH6514 for VGA. The input of VGA will come from other differential Amp or sonar sensor.
-. In datasheet, they see a sentense of…

Can you please advise if we can offer alternative to CLC5526MSA.
Thanks in advance

Hi Charles,
Are you able to use a digitally controlled amplifier? You only need analog if you need to minimize the phase delay. You could look at the LMH6514 instead.
Best regards,
Sean

I am looking for a PGA/VGA with a ac-coupled bipolar input swing. I have looked through the parts available…
Hi Donald,
The net impact of running the LMH6514 on +-4.5V supplies is a reduction in supply voltage of 1V. The input common mode range will shrink by 0.5V with respect to the negative supply and 0.5V with respect to the positive supply. Likewise…
Hello Amit,
Your circuit is configured correctly. AC coupling gives a lot of flexibility in supply configuration.
You mentioned 14dBm as a maximum input level. In a 50 Ohm system 14dBm is 3.2Vpp. This circuit has a gain of 4. That will overdrive…
Hello Beiping,
You would be using the LMH6514 model only to simulate the LMH6572 signal path performance. Hooman even showed how to incorporate the mux function into the TINA model. Hooman was not suggesting that you use an LMH6714 to replace the MUX…
