LTC6601CUF-1#TRPBF

Overview

The LTC6601CUF-1#TRPBF is a fully differential second-order active RC filter and driver manufactured by Analog Devices. It operates within a supply voltage range of 2.7V to 5.25V and features pin-configurable cutoff frequencies between 5MHz and 28MHz. The device offers programmable gain from -17dB to +17dB, with internal resistors and capacitors trimmed to 0.5% tolerance for consistent performance. It includes a three-state BIAS pin for power management, allowing selection between high performance, low power (50% reduction), and standby modes. The component is housed in a compact 4mm x 4mm 20-lead QFN package.

Feature Summary

• Pin-configurable filter response and gain settings
• Three-state BIAS pin for adjustable power consumption
• Rail-to-rail output swing with adjustable common mode voltage
• Low noise and distortion characteristics suitable for ADC drivers

Applications

• Differential input A/D converter driver
• Antialiasing and reconstruction filtering
• Single-ended to differential conversion and amplification
• Common mode voltage translation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'C' grade temperature range meets application requirements. Check for lead-free compliance documentation. Ensure the supplier provides valid traceability records. Validate that the part number matches the exact electrical specifications required for the design.

Selection Notes

Select this component for applications requiring precise, pin-strapped filter configurations without external passive components. Consider the BIAS pin functionality if power management across different operational states is necessary. Evaluate the 20-lead QFN package size against available PCB real estate. Ensure the supply voltage range aligns with the system's power rails.

Part Context

This part belongs to the LTC6601 family of active filters. The CU suffix denotes the commercial temperature grade. The UF indicates the 20-lead QFN package type. The #TRPBF suffix specifies tape and reel packaging with lead-free finish. This variant is designed for high-volume manufacturing integration.

Replacement Considerations

Direct replacements include other parts from the LTC6601 family with compatible packages and electrical characteristics. Verify pin compatibility and thermal performance before substitution. Consult manufacturer documentation for any updated revisions or recommended alternatives.
