MAX40661ATB/VY+

Overview

The MAX40661ATB/VY+ is a high-bandwidth automotive transimpedance amplifier designed for optical distance measurement receivers in LiDAR applications. It operates on a single +3.3V supply and features pin-selectable transimpedance gains of 25kΩ or 50kΩ. Optimized for input capacitances between 5pF and 12pF, it delivers a typical bandwidth of 160MHz at 10pF input capacitance. The device includes an internal input current clamp capable of handling up to 2A transient pulses and offers fast overload recovery. It supports low-power standby mode via the LP input and provides differential outputs.

Feature Summary

• Optimized for photodiode input capacitances ranging from 5pF to 12pF
• Features internal input current clamp for protection against high transient currents
• Includes low-power/standby control input to significantly reduce average power consumption
• Provides pin-selectable transimpedance gain values for flexible system design

Applications

• Optical Distance Measurement
• LiDAR Receivers
• Autonomous Driving Systems
• Automotive Applications

Procurement Notes

Verify the specific suffix /VY+ indicates automotive qualification with side-wettable flanks in the 10-lead TDFN package. Confirm the operating temperature range covers -40°C to +125°C. Ensure the ordering information matches the required bandwidth specifications for your application's input capacitance constraints.

Selection Notes

Select this component when interfacing with photodiodes exhibiting higher input capacitance (5pF–12pF). It is suitable for systems requiring fast overload recovery and low noise performance in automotive environments. Consider the MAX40660 if lower input capacitance (0.25pF–5pF) and higher bandwidth are required instead.

Part Context

This part belongs to the MAX40660/MAX40661 family of high-bandwidth transimpedance amplifiers. These devices are engineered specifically for LiDAR receiver front-ends, offering AEC-Q100 qualification. The MAX40661 variant distinguishes itself by being optimized for higher input capacitance scenarios compared to the MAX40660.
