Description

The MAX40662 is a 4-channel transimpedance amplifier for optical distance measurement receivers in light detection and ranging (LiDAR) applications. Low noise, high gain, low group delay, and fast recovery from overload make this quad TIA ideal for time-of-flight distance-measurement applications. The four input transimpedance stages are multiplexed to a pair of differential outputs. Important features include 2.1pA/ input-referred noise density, an internal current input clamp (up to 2A for 10ns pulses), pin-selectable 25kΩ and 50kΩ transimpedance, and wide 440MHz bandwidth. An offset current input allows optional output offset adjustment to the output voltage. A low-power/standby mode can be used to help reduce average power supply current between pulses.

The MAX40662 is available in a 16-pin, 4mm x 4mm, TQFN package with side-wettable flanks and is specified over the -40°C to +125°C automotive operating temperature range.
