MAX40660/MAX40661 High-Bandwidth Automotive Transimpedance Amplifier with Fast Output Recovery and Input Current Clamp for LiDAR General Description Benefits and Features The MAX40660/MAX40661 are transimpedance ampli- AEC-Q100 fiers for optical distance measurement receivers in LiDAR Enables ASIL Compliance (FMEDA Available upon applications. Low noise, high gain, low group delay, and Request) fast recovery from overload make these TIAs ideal for dis- MAX40660 tance-measurement applications. Important features in- Optimized for C = 0.25pF to 5pF IN clude 2.1pA input-referred noise density (MAX40660), an Bandwidth = 490MHz (typ) internal input clamp, pin-selectable 25k and 50k tran- MAX40661 simpedance, and wide bandwidth (490MHz (typ) for the Optimized for C = 5pF to 12pF IN MAX40660 with 0.5pF input capacitance and 25k tran- Bandwidth (C = 10pF) = 160MHz (typ), 100MHz IN simpedance 160MHz (typ) for the MAX40661 with 10pF (min) input capacitance). An offset current input allows optional Low Noise adjustment of input offset current. A low-power/standby Two Pin-Selectable Transimpedance Values control input reduces the supply current by better than 25k 80% to help reduce average power supply current be- 50k tween pulses. The MAX40660/MAX40661 transimped- ance amplifiers feature AEC-Q100 qualification over the Internal Clamp for Input Current up to 2A (Transient) -40C to +125C automotive operating temperature range Fast Overload Recovery: 2ns at 100mA and are available in a 3mm x 3mm, 10-lead TDFN pack- Offset Input Provides Offset Adjust Feature age with side-wettable flanks, making them excellent LP Input Reduces Power Dissipation Between Pulses choices for automotive LiDAR applications. 3.3V Operation 10-Pin TDFN (Side-Wettable) or Bare Die In addition to the TDFN package, the MAX40660 is avail- able as bare die.
