The LMH32401 device is a single-channel, differential output, high-speed transimpedance amplifier (TIA) that features several integrated functions geared towards light detection and ranging (LIDAR) and pulsed time-of-flight (ToF) systems. The LMH32401 device is designed to work with photodiode (PD) 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 LMH32401 device is offered in a space-saving 3-mm × 3-mm, 16-pin VQFN package and is rated over a temperature range from –40°C to +125°C.
