General Description

The MAX40660/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

2.1pA 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/MAX40661 transimpedance

amplifiers feature AEC-Q100 qualification over the

-40°C to +125°C automotive operating temperature range

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 is available

as bare die.
