LTC6560HUD#TRPBF

Overview

The LTC6560HUD#TRPBF is a single-channel transimpedance amplifier with output multiplexing, designed for LIDAR receivers using avalanche photodiodes. It features a 220MHz bandwidth and 74kΩ transimpedance gain. The device operates from a single 5V supply, consuming 90mW. Input current noise density is 4.8pA/√Hz at 200MHz with 2pF input capacitance. It supports a linear input range of 30µA and fast overload recovery in 10ns. The component is housed in a 3mm × 3mm 16-lead QFN package.

Feature Summary

• Integrates an output multiplexer to combine multiple devices into a single output channel
• Provides fast overload recovery to minimize data loss during saturation events
• Features low noise performance optimized for high-speed optical signal detection
• Includes internal series resistance for driving back-terminated transmission lines

Applications

• LIDAR receiver systems
• Industrial imaging applications
• Time-of-flight detectors

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the HUD designation corresponds to the extended temperature range requirements for your environment. Ensure compatibility with automotive quality standards if applicable by checking for the W suffix variant. Validate that the lead-free finish meets your assembly process specifications.

Selection Notes

Select this component for designs requiring high bandwidth and low noise in a compact form factor. Consider the output multiplexing capability if space constraints prevent individual outputs for each sensor channel. Evaluate the total input capacitance to ensure the desired bandwidth is maintained. Verify power supply requirements align with the single 5V operation specification.
