説明

EE-Sim^®を使って設計とシミュレーションを行う:

The MAX40660 and 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 2.38pA 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 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, making them excellent choices for automotive LiDAR applications.

In addition to the TDFN package, the MAX40660 and MAX40661 are available as bare die, and are specified over the -40°C to +125°C automotive operating temperature range.
