The LMH32404 is a quad-channel, differential output, high-speed transimpedance amplifier (TIA) geared towards light detection and ranging (LIDAR) and laser distance measurement systems. Each LMH32404 channel has integrated switches on the output to disconnect the differential output amplifier from the output pins. This enables the LMH32404 to be highly configurable in a multi-channel LIDAR system. The LMH32404 device is designed to work with photodiodes (PDs), for example avalanche photodiodes (APDs), connected in configurations that can source or sink the current. When the photodiode sinks the photocurrent (anode is biased to a negative voltage and cathode is tied to the amplifier input) the fast recovery clamp activates when the amplifier input is overloaded. When the photodiode sources the photocurrent (cathode is biased to a positive voltage and anode is tied to the amplifier input) a soft clamp activates when the amplifier input is overloaded. When the soft clamp activates the amplifier takes longer to recover. The recovery time depends on the level of input overload. The LMH32404 is offered in a space-saving 5-mm × 4-mm, 28-pin VQFN package and is rated over a temperature range from –40°C to +125°C.
