The LMH34400 is the industries’ smallest, fixed-gain, single-ended transimpedance amplifier for light detection and ranging (LIDAR) applications and laser distance measurement systems. The LMH34400 produces 1.0 V PP of output swing and has an input-referred noise of 50 nA RMS.

The LMH34400 has an integrated 100‑mA clamp that protects the amplifier and allows the device to recover rapidly from an overloaded input condition. The LMH34400 also features an integrated ambient light cancellation (ALC) circuit that can be used instead of ac coupling between the photodiode and the amplifier to save board space and system cost. Disable the ALC loop in cases where the frequency signal content to be measured is less than 400 kHz.

When the amplifier is not being used, the LMH34400 can be placed in low-power mode using the EN pin to conserve power. This feature allows several LMH34400 amplifiers to be multiplexed to the input of the next stage of the receive signal chain with the EN control pin serving as the multiplexer select function. The LMH34400 offers a single-ended output and is optimized for use with time-to-digital converter (TDC) based LIDAR systems.
