LTC6560IUD#PBF

Overview

The LTC6560IUD#PBF is a single-channel transimpedance amplifier with output multiplexing, designed for low-noise applications. It features a 220MHz bandwidth and 74kΩ transimpedance gain. The device operates from a single 5V supply with 90mW power dissipation. 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. The component is housed in a 16-lead 3mm × 3mm QFN package.

Feature Summary

• Integrated output multiplexer allows combining multiple devices into a single output channel
• Fast overload recovery minimizes data loss during saturation events
• Low impedance op amp style output drives back-terminated cables
• Single 5V supply operation with low power consumption

Applications

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

Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel packaging. Confirm the I grade temperature range meets system requirements. Check automotive versions if AEC-Q100 qualification is required. Ensure ordering information matches the exact package type.

Selection Notes

Select this part for high-speed optical detection requiring low noise and wide dynamic range. Consider the output MUX feature for multi-channel designs without external switches. Evaluate total input capacitance to ensure bandwidth targets are met. Verify thermal management capabilities within the QFN package.

Part Context

This component belongs to the LTC6560 family of transimpedance amplifiers. It is specifically optimized for LiDAR applications using APDs. The IUD variant denotes the industrial temperature range and plastic QFN package. It complements other Analog Devices optical signal processing solutions.

Replacement Considerations

Direct replacements include the LTC6560H for extended temperature ranges or the automotive-grade LTC6560HUD. Verify pin compatibility and electrical specifications before substitution.

FAQ

How does the output MUX function work?

The O_MUX pin controls the output multiplexer. When low, the output is enabled; when high, the input is decoupled from the output, allowing multiple devices to share a common output line.

What is the maximum overload current recovery time?

The device recovers from a 1mA input pulse overload in approximately 10ns without phase reversal.
