MAX40660A/D+

Overview

The MAX40660A/D+ is a high-bandwidth transimpedance amplifier (TIA) designed for optical distance measurement receivers in LiDAR applications. It features low noise, high gain, and fast recovery from overload. The device operates at 3.3V with an operating temperature range of -40°C to +125°C. Key electrical parameters include a typical bandwidth of 490MHz with 0.5pF input capacitance and 25kΩ transimpedance. Input-referred noise density is 2.1pA/√Hz. It supports pin-selectable transimpedance values of 25kΩ and 50kΩ. The part is available as bare die.

Feature Summary

• Optimized for low input capacitance ranging from 0.25pF to 5pF
• Features internal input current clamp for transient protection up to 2A
• Includes low-power standby control input to reduce supply current by over 80%
• Provides offset adjustment capability via dedicated input pin

Applications

• Optical Distance Measurement
• LiDAR Receivers
• Industrial Safety Systems
• Autonomous Driving Systems

Procurement Notes

Verify the specific ordering suffix to confirm package type and availability status. The 'A/D+' designation indicates a bare die form factor intended for direct integration into custom substrates or flip-chip assemblies rather than standard surface-mount packages. Confirm automotive qualification requirements and FMEDA documentation availability if ASIL compliance is required for the target application.

Selection Notes

Select this component when designing optical receivers requiring minimal input capacitance optimization between 0.25pF and 5pF. The MAX40660 variant offers higher bandwidth compared to the MAX40661, making it suitable for applications demanding faster signal processing. Ensure the design accommodates the 3.3V supply requirement and utilizes the differential output configuration for optimal noise rejection.

Part Context

This component belongs to the MAX40660/MAX40661 family of high-bandwidth automotive transimpedance amplifiers manufactured by Analog Devices Inc./Maxim Integrated. These devices are specifically engineered for LiDAR systems, offering fast overload recovery and low group delay. The family includes both packaged TDFN versions and bare die options to support various manufacturing and integration needs.
