I try to use LMH6624 to make a prea-amp for a piezoelectric sensor. I chose it for the wide band and low noise characteristics. I tried to use it in a traditional circuit where imput resistor is 1M or higher. Due to high bias current it blocked the OA…

I got the below question:
I want to use Ultra Low Noise Op. AMP LMH6629 or LMH6624 instead of ADA4899, When I download PSPice mode I have to files inside *.MOD and *.txt .please advice witch file is fit…
Hi,
I've not verified this with simulation, but if you used a low noise device on the front, you should get higher SNR. Here are a couple of possibilities which work with 10V supplies:
OPA847 (0.85nV/RtHz, 2.5pA/RtHz, 3.9GHz GBW)
LMH6624 (0.92nV/RtHz…

I'm now developing a system which combines two different types of sensors: ultrasonic and impedance sensors. In the system to achieve high-speed acquisition both of the…
Hi Jamaal,
Your other choices are the following, which you can find by using SelGuide:

LMH6629 (0.69nV/RtHz, limited to 5V total supply voltage, 140MHz with Av= 30V/V)
LMH6624 (0.9nV/RtHz, 50MHz with Av=30V/V)

Other Parts Discussed in Thread: OPA699 , OPA847 , LMH6624 , LMH6642 , OPA656 Hello, I'm Luca.
I'm designing a transimpedance with OPA699. Power supply is between 0V and +5V and the output limiters are +3V and +2V.
Everything work well untill the OPA699…
Part Number: LMH6642 Other Parts Discussed in Thread: TINA-TI I would like to use the PSPICE model of LMH6642 to perform a simulation.
When I downloaded the PSPICE model, it only contained a text file and .MOD file.
Is there a .lib file for LMH6642?
