Description
General part information
LMH32404 Series
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. The LMH32404 also features an integrated ambient light cancellation (ALC) circuit on each channel that can be used instead of AC coupling between the photodiode and the amplifier to save board space and system cost. The ALC loop should be disabled when DC and low frequency content is measured.
Each LMH32404 channel has integrated switches on the output to disconnect the differential output amplifier from the output pins and put the channel in standby mode. When switching between different channels, the transistion time is only 10 ns. The LMH32404 can be placed in low-power mode using theENpin to conserve power when the amplifier is not being used.
