Amplifiers

quad TIAdifferential outputLiDAR350 MHzVQFN-28

LMH32404IRHFR is a 3.3 V quad differential-output TIA for photodiode LiDAR and laser-ranging front ends, with per-channel output switching and integrated input clamps.

Best for

  • Multi-channel LiDAR receivers
  • Laser distance measurement front ends
  • Photodiode arrays with output multiplexing

Avoid if

  • Low-frequency DC measurement requires an active ambient-light cancellation loop
  • Photodiode capacitance or layout parasitics exceed the bandwidth budget
  • A sourcing photodiode configuration requires fast overload recovery

Check before use

  • Photodiode current direction and overload behavior
  • ADC differential input impedance and common-mode voltage
  • Decoupling placement and input/output parasitic capacitance
