Transimpedance Amplifiers

The MAX40658 and MAX40659 are transimpedance amplifiers for optical distance measurement receivers for LiDAR applications. Low noise, high gain, low group delay, and fast recovery from overload make these parts ideal for distance-measurement applications.Important features include 45nARMS input-referred noise, an internal 100mA clamp, 18kΩ (MAX40658) and 36kΩ (MAX40659) transimpedance, and greater than 360MHz bandwidth. An offset input allows adjustment of input offset current. Operating from a +3.3V supply, the MAX40658 and MAX40659 consume only 70mW.The MAX40658 and MAX40659 are available in a 3mm x 3mm, 8-pin TDFN package or bare die, and are specified over the -40°C to 85°C operating temperature range. 45nARMS NoiseTwo Transimpedance Values Available18kΩ (MAX40658)36kΩ (MAX40659) 360MHz Minimum BandwidthInternal Clamp For Input Current Up To 100mAOffset Adjust Input70mW Power Dissipation3.3V Operation ApplicationsAutonomous Driving SystemsIndustrial Safety SystemsLIDAR ReceiversOptical Distance Measurement

Transimpedance Amplifiers, Texas Instruments Transimpedance Amplifiers A range of dedicated Transimpedance amplifiers designed for current-to-voltage conversion. These devices are used in applications such as photo detector amplifiers and accelerometer interfaces where an output voltage is desired from a current generating source.
