General Description

The LMH32404 is a quad-channel, single-ended-input to differential-output transimpedance amplifier (TIA) for light detection and ranging (LIDAR) applications and laser distance measurement systems.

The LMH32404 has an integrated 100-mA clamp on each channel that protects the amplifier and allows the device to recover rapidly from an overloaded input condition.
