Part Number: LMH32401 Hi Team,
As for LMH32401' feature ALC, could you give more detail about this?
•Integrated ambient light cancellation
What's the meaning of ambient light mentioned here? including the sunlight or the APD noise?
Part Number: LMH32401 due to my customer APD -VBIAS do not support negative voltage. they want to check whether LMH32401 could connect with APD negative pin to realize the function?
it seem our VIN will keep 2.47V VBIAS, because internal have this voltage…
Part Number: LMH32401 Other Parts Discussed in Thread: TINA-TI , Hi!
I make a simulation of the LMH32401 with TINA-TI, to assess its performance, and I use the most recent model SBOMB18B.TSC proposed in the www.ti.com/.../LMH32401 I have some examples of…
Part Number: LMH32401 Dear Sir,
How could I connect LMH32401 with a negative voltage and APD. Is the below circuit OK? The (Out+)- (Out-) is in accordance with the APD current, right?
And could you please give me some guidance(with picture) if my connection…
Hello Andrianirina,
The main advantage of having a differential TIA such as the LMH32401 is the ability to interface with a differential ADC without having to add an extra FDA stage. Fully-differential amplifers also have the ability to have a larger…
Part Number: LMH32401 Other Parts Discussed in Thread: OPA857
Hi,
Regarding ambient light cancellation, I see that the cutoff frequency is around 100kHz, which is way, way too much for me.
I'm aiming for a cutoff frequency around 600Hz.
In other…
Part Number: LMH32401 Other Parts Discussed in Thread: OPA857 , Hello together,
we're busy designign our own OTDR application related to TI's refernce design. In this application OPA857 is used as TIA for a connected APD.
Because of spacing requirements…
