MAX40660ATB/VY+

Overview

The MAX40660ATB/VY+ is a high-bandwidth transimpedance amplifier designed for optical distance measurement receivers in LiDAR applications. It operates on a single +3.3V supply and features AEC-Q100 qualification over the -40°C to +125°C automotive temperature range. The device offers pin-selectable transimpedance values of 25kΩ or 50kΩ, an internal input current clamp capable of handling up to 2A transient pulses, and fast overload recovery. It includes a low-power standby mode that reduces supply current by more than 80% and provides differential outputs optimized for driving high-speed ADCs.

Feature Summary

• Automotive-grade reliability with AEC-Q100 qualification and ASIL compliance support
• Pin-selectable transimpedance gain configuration for flexible system design
• Internal input current clamp protects against high-energy transient pulses
• Low-power standby control significantly reduces average power consumption between pulses

Applications

• Optical Distance Measurement
• LiDAR Receivers
• Autonomous Driving Systems

Procurement Notes

Verify the specific suffix /VY+ indicates the automotive-qualified version with side-wettable flanks in the 10-lead TDFN package. Confirm the operating temperature range matches the required -40°C to +125°C specification. Ensure the ordering information aligns with the latest Analog Devices datasheet revision to avoid discrepancies in package marking or electrical characteristics.

Selection Notes

Select this component for applications requiring high bandwidth and low noise in compact automotive environments. The MAX40660 variant is optimized for lower input capacitance (0.25pF to 5pF), making it suitable for photodiodes with minimal parasitic capacitance. Consider the differential output interface requirements and the need for AC coupling or specific termination strategies when integrating with downstream analog-to-digital converters.

Part Context

This part belongs to the MAX40660/MAX40661 family of high-bandwidth transimpedance amplifiers. It is specifically engineered for LiDAR systems where fast response times and robust overload recovery are critical. The device integrates both the transimpedance input stage and a voltage amplifier/output buffer into a single compact package, simplifying the receiver circuit design for optical sensing applications.
