Part Number: LMH6629SDEVAL Other Parts Discussed in Thread: LMH6629 Hi TI employees：
I used LMH6629 to design the amplifying circuit，the amplifier circuit has a total of eight channels, using eight LMH6629，we have a very strange problem
First of all…
Part Number: LMH6629SDEVAL Other Parts Discussed in Thread: LMH6629 I just received this evaluation board for the LMH6629 amp. I wired it up with +2.5V V+, Gnd, and -2.5V on V- (verified with multimeter).
When I have a signal input to IN+ I can see…
Part Number: LMH6629SDEVAL So I have the LMH6629SDEVAL board, and I am just trying to turn the amplifier on to get some performance specs. I did not physically alter any components on the board, so all of the resistor values and such are still to spec…
Hi Dillon,
400 MHz will be challenging for the LMH6629, but it should be possible to get close to that value while keeping the amplifier stable. The most important piece of information will be to narrow down the input capacitance value in order to make…
Hi Troung,
Yes, there is a populated board for the LMH6629 set for a gain of 10V/V (but can be changed by changing board components) that you can use:
I have copied your original conditions below for reference:
"We would like to design an amplifier…
Hi Jason,
With your TINA circuit, I measure 13nV/RtHz output noise at VF1 or 26nV/RtHz at device output. The 1kohm PIN diode biasing resistor (R2) contributes 21nV/RtHz [4.07nV/RtHz x (5k / 1k) ]. Is that an external resistor in your circuit or built…
