MAX40660/MAX40661 Transimpedance Amplifier with 100m A Input Current Clamp for Automotive Li DAR General Description The MAX40660 and MAX40661 are transimpedance amplifiers 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 2.38p A input-referred noise density (MAX40660), an internal input clamp, pin-selectable 25kΩ and 50kΩ transimpedance, and wide bandwidth (490MHz (typ) for the MAX40660 with 0.5p F input capacitance and 25kΩ transimpedance; 160MHz (typ) for the MAX40661 with 10p F 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 pliance, and are available in a 3mm x 3mm,10-lead TDFN package with side-wettable flanks, making them excellent choices for automotive Li DAR 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.
