LTC6560IUD#TRPBF

Overview

The LTC6560IUD#TRPBF is a single-channel transimpedance amplifier with output multiplexing, packaged in a 16-lead 3mm × 3mm QFN. It operates from a single 5V supply and dissipates 90mW. The device provides a typical transimpedance gain of 74kΩ and supports a linear input current range of 0µA to 30µA. It features a 220MHz bandwidth with 2pF input capacitance and an input current noise density of 4.8pA/√Hz at 200MHz. The component handles overload currents exceeding ±400mA peak and recovers within 10ns. It includes an internal 50Ω series resistor at the OUTTERM pin for driving back-terminated cables.

Feature Summary

• Integrates a low-noise transimpedance amplifier optimized for avalanche photodiode applications
• Features an output multiplexer allowing multiple devices to combine into a single output channel
• Provides fast overload recovery and rapid output switching capabilities
• Includes an internal series resistor at the output terminal for direct cable driving

Applications

• LIDAR receivers utilizing avalanche photodiodes
• Industrial imaging systems
• Time-of-flight detectors

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the I grade temperature range meets system requirements. Ensure the 16-lead QFN footprint matches the PCB layout. Check for automotive qualified variants if required by the application standards.

Selection Notes

Select this component for designs requiring high bandwidth and low noise in a compact form factor. The integrated output MUX simplifies multi-channel architectures by eliminating external switches. Consider the 74kΩ gain for matching APD signal levels. Verify that the 5V single supply constraint aligns with the system power rails.
