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, we…
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 the…
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…
Part Number: LMH6629 I have the two components mentioned above, and was curious to know if I could use the LMH6629, in the first stage, as a trans-impedance amplifier, which will take input current from a PMT, or an APD, (which will have an intrinsic…
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…
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:
