The MAX40658 and MAX40659 are transimpedance amplifiers for optical distance measurement receivers for LiDAR applications. Low noise, high gain, low group delay, and fast recovery from overload make these parts ideal for distance-measurement applications.

Important features include 45nA_RMS input-referred noise, an internal 100mA clamp, 18kΩ (MAX40658) and 36kΩ (MAX40659) transimpedance, and greater than 360MHz bandwidth. An offset input allows adjustment of input offset current. Operating from a +3.3V supply, the MAX40658 and MAX40659 consume only 70mW.

The MAX40658 and MAX40659 are available in a 3mm x 3mm, 8-pin TDFN package or bare die, and are specified over the -40°C to 85°C operating temperature range.
