LTC6563HUDDM#PBF-ES

Overview

The Analog Devices LTC6563HUDDM#PBF-ES is an engineering sample of a four-channel transimpedance amplifier with integrated output multiplexing. It features a 600MHz bandwidth and selectable transimpedance gains of 22.2kΩ, 16.7kΩ, 11.1kΩ, or 5.55kΩ. The device provides a linear input current range up to 90µA and supports fast channel switching and overload recovery. It includes a built-in high-speed differential ADC driver capable of swinging up to 2VP-P into a 100Ω load. The component operates on a 3.3V supply with power dissipation ranging from 194mW to 325mW depending on the output mode.

Feature Summary

• Four-channel architecture with internal 4-to-1 multiplexer for simplified system design
• Low noise performance suitable for avalanche photodiode applications
• Built-in high-speed differential output stage driving external loads
• Fast transient response with rapid overload recovery capabilities

Applications

• Automotive LIDAR receivers
• Industrial LIDAR receivers
• Photodiode signal conditioning circuits

Procurement Notes

Verify that the suffix -ES indicates this unit is an Engineering Sample rather than a production-grade component. Confirm that the specific lot meets your reliability requirements, as engineering samples may not undergo the same rigorous qualification testing as standard commercial or automotive grade parts. Ensure compatibility with your manufacturing processes before finalizing integration plans.

Selection Notes

Select this component when designing multi-channel optical sensing systems requiring high bandwidth and low noise. The integrated multiplexer reduces external component count compared to discrete solutions. Consider the available gain settings to match the expected photocurrent levels of your specific photodiode array. Evaluate the thermal management requirements given the maximum power dissipation specifications under full load conditions.

Part Context

This part belongs to the LTC6563 family of transimpedance amplifiers manufactured by Analog Devices. The HUDDM designation specifies the high-temperature industrial grade variant packaged in a 24-lead QFN format. The #PBF suffix denotes lead-free packaging compliant with environmental directives. This series is engineered specifically for high-speed optical detection applications where signal integrity and channel isolation are critical.
