LTC6560HUD#PBF

Overview

The LTC6560HUD#PBF is a single-channel low-noise transimpedance amplifier with an output multiplexer, 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 and rapid output switching for high-speed applications
• Features low noise performance optimized for small signal detection
• Includes internal series resistor at the output terminal for impedance matching

Applications

• LIDAR receivers utilizing avalanche photodiodes
• Industrial imaging systems requiring precise current measurement
