LTC6560HUD#WPBF

Overview

The LTC6560HUD#WPBF 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 0µA to 30µA and fast overload recovery in 10ns. The component is AEC-Q100 qualified and housed in a 3mm × 3mm 16-lead 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 noise performance optimized for high-speed optical signal detection
• Automotive-grade qualification ensures reliability in demanding environments

Applications

• LIDAR receiver systems

Procurement Notes

Verify the specific #WPBF suffix indicates automotive grade manufacturing controls. Confirm the operating temperature range matches system requirements. Ensure the 16-lead QFN package footprint aligns with PCB layout constraints. Check for RoHS compliance documentation. Validate that the supplier provides official Analog Devices traceability reports.

Selection Notes

Select this component when designing multi-channel LIDAR arrays requiring compact solutions without external multiplexers. Consider the trade-off between input capacitance and bandwidth. Evaluate the need for AC versus DC coupling based on dynamic range requirements. Assess power dissipation limits within the thermal design. Verify compatibility with time-to-digital converters or ADCs.
