6.1 Overview

The LMH34400 is a single-channel, single-ended output, high-speed transimpedance amplifier (TIA) and features several integrated functions geared towards light detection and ranging (LIDAR) and pulsed time-of-flight (ToF) systems. The LMH34400 is designed to work with photodiode (PD) anodes that are biased to a negative voltage and cathodes that are tied to the amplifier input; therefore, the amplifier sources the photocurrent. The LMH34400 is offered in a space-saving 1.6‑mm × 1.6‑mm, 6‑pin SOT5X3 package and is rated over a temperature range from –40°C to +125°C.
