LTC6563HUDDM#WTRPBF

Overview

The LTC6563HUDDM#WTRPBF is a quad-channel transimpedance amplifier designed for optical signal processing. It features a 600 MHz 3dB bandwidth and a 3000 V/us slew rate, supporting high-speed data transmission. The device operates on a single supply voltage ranging from 3.15 V to 3.45 V with a typical operating current of 34 mA. It offers differential inputs and outputs, low input noise current density of 3.7 pA/√Hz, and a power supply rejection ratio of 38 dB. Packaged in a QFN-24 format, it supports an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates four independent transimpedance amplifiers within a single compact package for multi-channel optical detection.
• Provides differential output signals to improve common-mode noise rejection in high-speed applications.
• Includes a dedicated shutdown pin to minimize power consumption during inactive periods.

Applications

• Lidar receiver front-ends utilizing avalanche photodiodes (APDs)
• Optical communication systems requiring high-bandwidth signal conditioning
• Multi-channel photodetector arrays for industrial sensing

Procurement Notes

Verify the specific suffix WTRPBF indicates tape-and-reel packaging when ordering. Confirm AEC-Q100 qualification status if automotive compliance is required. Ensure the QFN-24 footprint matches the target PCB layout. Validate that the 3.15 V to 3.45 V supply range aligns with system power rails. Check for any recent product change notifications affecting pinout or electrical characteristics.

Selection Notes

Select this component when four independent channels are necessary for parallel optical signal acquisition. The 600 MHz bandwidth suits applications demanding fast rise times and wide dynamic range. Differential outputs are preferred for reducing electromagnetic interference in dense layouts. The integrated shutdown feature aids in managing thermal constraints in enclosed environments.

Part Context

This part belongs to the LTC6563 series of high-speed transimpedance amplifiers manufactured by Analog Devices. It is distinct from single-channel variants like the LTC6560 and other family members such as the LTC6561, which offer different bandwidth and output configurations. The HUDDM designation specifies the high-temperature grade and QFN-24 package type.

Replacement Considerations

Direct substitutes include other quad-channel TIAs from the same manufacturer. Verify compatibility regarding pinout, supply voltage requirements, and bandwidth specifications before swapping components.
