Part Number: LMH32401 Hi Team,
May I ask if the -VBIAS of LMH32401 connect to GND directly, what will the negative bias be between Vin- and Vin+?
If using PD instead of APD, there is no need for a large negative bias, about -0.5V is enough.

"the input trace can be used to connect a common three-terminal photo-diode in a TO package. The photo-diode can be mounted over the edge of the board where the cathode can be connected…
Part Number: LMH32401 Other Parts Discussed in Thread: OPA858 Hi team,
My customer have some questions about LMH32401:
1.LMH32401 is mainly used in lidar ranging. At present, most lidars are TOF, and the waves are pulsed lasers, but there are also FMCW…
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 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: LMH32404RHFEVM Other Parts Discussed in Thread: LMH32401 , LMH32404 Tool/software: What modifications are required to connect APD or other photodiodes to this kit for evaluation? Can I simply change the AC coupling capacitor or series resistor…
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…
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…
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…
