Hello Ezira,
Sorry for the delay, we are still experimenting in the lab. This type of application probably would not be as simple as in-series capacitors at the input pin without affecting the signal fidelity of the input current. However, this e2e thread…
Hello Ezira,
I apologize for the very long delay in response. You are correct, there shouldn't be an issue with using your photodiode with this device.
The datasheet does show around 1.3pF if you apply a 5V reverse voltage, which is similar to the…
Part Number: LMH32404RHFEVM Other Parts Discussed in Thread: LMH32404 Tool/software: Could you please walk me through the design logic with the 1:1 balun on the output of this eval kit?
The LMH32404 has a differential output impedance of 21 ohms, and…
Part Number: LMH32404 Greetings,
I have conducted a noise simulation for the LMH32404 in LTspice. Please refer to the schematic and results provided below.
The noise results show a significant deviation from the input noise indicated in the datasheet…
Part Number: LMH32404
HI,
For the LMH32404 is it possible to connect VCC to zero volt and GND to -3.3V.
This is in order to amplify input currents that are sourced (not sinked) from the photodetector
Thanks,

Part Number: LMH32404RHFEVM Other Parts Discussed in Thread: LMH32404
Hello,
I looked into the schematic of the LMH32404RHFEVM.
Is there any chance that the output baluns (transformers from Coilcraft : JA4220-ALB have been connected in the wrong way? …

Hello,
1. I've noticed that the Pspice model of LMH32404 doesn't seem to support VOD. Regardless of the voltage value connected to this pin in simulations, the output waveform…
Hello Ahmet,
Glad to hear more updates and additional information. What type of wearable project are you working on? The application would have some affect into the granularity of recommendations I can make. In the meantime, below is some additional information…
Part Number: LMH32404 Hello,
Can the LMH32404 have its input current signal sourced by a photodetector (instead of being sinked)?
In other words:
Can the LMH32404 support input current flowing into the device by connecting the VCC to 0V and the GND to…
