Analog Devices / Maxim Integrated MAX40660 & MAX40661 Transimpedance Amplifiers

Analog Devices MAX40660 and MAX40661 Transimpedance Amplifiers are for optical distance measurement receivers in Li-DAR applications. Low noise, high gain, low group delay, and fast recovery from overload make these TIAs ideal for distance-measurement applications. Important features include 2.38pA input-referred noise density (MAX40660), an internal input clamp, pin-selectable 25kΩ and 50kΩ transimpedance, and wide bandwidth. An offset current input allows optional adjustment of input offset current. A low-power/standby control input reduces the supply current by over 80% to help reduce the average power supply current between pulses. Analog Devices MAX40660 and MAX40661 Transimpedance Amplifiers feature AEC-Q100 qualification, enable ASIL compliance, and are available in a 3mm x 3mm, 10-lead TDFN package with side-wettable flanks. This makes these devices excellent choices for automotive LiDAR applications.
