LTC6601CUF-2#TRPBF

Overview

The LTC6601CUF-2#TRPBF is a low power, low distortion, fully differential second-order active broadband RC filter and driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7V to 5.25V and features pin-configurable cutoff frequencies between 5MHz and 27MHz. The device offers programmable gain from -17dB to +17dB and includes an adjustable output common mode voltage with rail-to-rail output swing. Internal resistors and capacitors are trimmed to 0.5% accuracy for consistent performance. It 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 power consumption adjustment
• Integrated on-chip passive components trimmed for accuracy
• Differential A/D converter driver capability

Applications

• Antialiasing and reconstruction filtering
• Single-ended to differential conversion and amplification
• Low voltage, low noise differential signal processing
• Common mode voltage translation
• Portable instrumentation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C as specified in the ordering information. Ensure compatibility with the 20-lead QFN footprint during procurement planning.

Selection Notes

Select the LTC6601-2 variant over the LTC6601-1 when lowest distortion at high frequencies is required, as the -2 option prioritizes distortion performance while the -1 focuses on lowest noise. Consider the BIAS pin configuration to balance between low power operation and high performance based on system requirements.

Part Context

This component belongs to the LTC6601 family of active filters and ADC drivers. It is designed to replace discrete RC filter solutions by integrating precision passive components and amplifiers into a single package. The part serves as a bridge between analog signal sources and high-speed data converters.
