Part Number: LMP7717 Other Parts Discussed in Thread: OPA320 Hello,
I am using LMP7717 as a buffer (voltage follower) in my project. Below, I added the oscilloscope images of the voltage levels on each pin and circuit schematic . why is the output voltage…
Other Parts Discussed in Thread: LMP7717 Hi.
I need a unity gain buffer when input signal is 50MHz, max 1.8V min 0V square wave. and I need to use single voltage supply 1.8V...
So I surf in TI products, I found LMP7717. I followed the application…
Hi Samir, Thank you so much for your explanation. So, the 2nd pole before the unity gain frequency increases high frequency noises (from 300kHz to 20 MHz) at the output voltage, cf Fig. 5. For our application, we need to detect a current of 0.3 µA at…
Other Parts Discussed in Thread: LMP7717 , OPA320 , LMP7701 , LMP7715 Hi,
We are using LMP7717 as Unity gain amplifier. The datasheet says if gains<10 , op-amp should be externally compensated. But the values are mentioned based on Rf as non-zero…
Part Number: OPA818 Other Parts Discussed in Thread: LMP7717 , TINA-TI
Dear Engineers,
We want to design a transimpedance amplifier with a gain over 1G V/A, and we also want its bandwidth to be as high as possible. We already know the impact of input…
You will get more dynamic range using a decompensated device like the LMP7717,
There is a section in this article on transimpedance design - no way to pursue this query without a source capacitance number. The end of this article includes tables of…
Part Number: OPA365 Other Parts Discussed in Thread: , LMV793 , OPA607 , LMP7717 , Also, could someone from TI provide me with an update on lead times/stocking levels at TI and distys for OPA365AIDBVT.
Also Rachel, that LMP7717 is going to show up in a July article where I had built tables of decomp parts. The TINA model actually shows a true GBP of 109Mhz on that device - you would use that in Eq.1 in prior post,
Yea Shweta,
What you draw looks like a standard transimpedance design if you are driving into the inverting summing junction of an op amp. If you are looking at clouds, unlikely you need the speed of the LMH6642.
Normally, you would use a decompensated…
