The MAX40213 is a transimpedance amplifier for optical distance measurement receivers in LiDAR applications. Low noise, high gain, low group delay, and fast recovery from overload make this TIA ideal for distance-measurement applications. Important features include 1.1pA/√Hz input-referred noise density, an internal 2A input clamp, pin-selectable 150kΩ and 750kΩ transimpedance (into a 1kΩ load), and wide bandwidth (300MHz, typ). An offset current input allows optional adjustment of input offset current. The MAX40213 has a shutdown (SD) control input that reduces the supply current to 0.01μA. This transimpedance amplifier is available in a 8-bump WLP, and is specified over the -40°C to +85°C operating temperature range.
