描述

The MAX40660/MAX40661 are transimpedance amplifiers for optical distance measurement receivers in LiDAR applications. Low noise, high gain, low group delay, and fast recovery from overload make these TIAs ideal for distance-measurement applications. Important features include 2.1pA input-referred noise density (MAX40660), an internal input clamp, pin-selectable 25kΩ and 50kΩ transimpedance, and wide bandwidth (490MHz (typ) for the MAX40660 with 0.5pF input capacitance and 25kΩ transimpedance; 160MHz (typ) for the MAX40661 with 10pF input capacitance). An offset current input allows optional adjustment of input offset current. A low-power/standby control input reduces the supply current by better than 80% to help reduce average power supply current between pulses. The MAX40660/MAX40661 transimpedance amplifiers feature AEC-Q100 qualification over the -40°C to +125°C automotive operating temperature range and are available in a 3mm x 3mm, 10-lead TDFN package with side-wettable flanks, making them excellent choices for automotive LiDAR applications.

In addition to the TDFN package, the MAX40660 is available as bare die.
