LTC6605CDJC-10#PBF

Overview

The LTC6605CDJC-10#PBF is a dual-channel active filter and differential amplifier manufactured by Analog Devices. It integrates two matched second-order low-pass filters with a 10MHz cutoff frequency, utilizing internal laser-trimmed resistors and capacitors to ensure precise gain and phase matching between channels. The device operates on a single supply voltage ranging from 2.7V to 5.25V and draws 39mA of operating current. It features an input voltage noise density of 14nV/√Hz and a common-mode rejection ratio (CMRR) of 50dB. Packaged in a 22-lead DFN (DFN-22) surface-mount enclosure, it is designed for applications requiring high precision and low distortion.

Feature Summary

• Integrates two internally matched second-order low-pass filters with integrated differential amplifiers
• Utilizes internal laser-trimmed components to achieve precise gain and phase matching between channels
• Provides low noise performance suitable for high-fidelity signal processing applications

Applications

• High-speed data acquisition systems requiring matched filtering
• Instrumentation and measurement equipment
• Medical imaging signal conditioning

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Check for discontinuation notices as this part may be subject to end-of-life status. Ensure compatibility with existing PCB footprints and design specifications before procurement.

Selection Notes

Select this component when dual-channel matched filtering is required within a compact footprint. Compare against other members of the LTC6605 family for different cutoff frequencies such as 14MHz variants. Evaluate power consumption constraints against the 39mA operating current. Consider the DFN-22 package dimensions for thermal management and board space limitations.

Part Context

This component belongs to the LTC6605 series of dual matched filter/amplifiers. It shares architectural similarities with other parts in the family but differs in cutoff frequency specifications. The device is distinct from single-channel differential amplifiers like the LT6600. It serves as a specialized solution for applications demanding tight channel-to-channel matching without external trimming.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify availability of alternative cutoff frequency variants within the same series if exact specifications cannot be met.
