  • LMH32404-Q1: My application mounts an APD array in a package beside the LMH32404.

    Part Number: LMH32404-Q1 Other Parts Discussed in Thread: LMH32404 , , LMH32401 The circuit includes an APD array, internal package traces to a package pins, then a trace to an 0201 resistor, then a trace to the LMH32404 input pin. Do you have charts of…

  • RE: LMH32404: When using this amplifier in parallel output in a ToF radar array, it is found that there is a voltage step problem in the TIA output at the moment of switching between different channels or switching between different devices

    Hello Jin, Does this voltage step occur only during a switching period between channels (i.e. changing logic level on M1-M4 pins)? Is this consistent for all channels (CH3 and CH4) and for all devices (4 of the LMH32404 in your schematic)? Are you using…
