LTC6601IUF-2#PBF

Overview

The LTC6601IUF-2#PBF is a low power, low distortion, fully differential 2nd 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 ranging from -17dB to +17dB and includes an integrated three-state BIAS pin for adjusting amplifier power consumption across low power, high performance, and standby modes. Packaged in a compact 4mm × 4mm 20-lead QFN, it provides rail-to-rail output swing and adjustable output common mode voltage.

Feature Summary

• Pin-configurable filter response and gain settings
• Three-state BIAS pin for power optimization
• Integrated on-chip resistors and capacitors trimmed for accuracy
• Rail-to-rail output with adjustable common mode voltage

Applications

• Differential A/D converter driver
• Antialiasing and reconstruction filtering
• Single-ended to differential conversion and amplification
• Portable instrumentation signal processing

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the I-grade designation ensures guaranteed performance over the specified industrial temperature range. Check current availability status as distribution channels may vary for this component type.

Selection Notes

Select the LTC6601-2 variant when lowest distortion at high frequencies is required, distinguishing it from the LTC6601-1 which prioritizes lowest noise. Ensure the application benefits from the fully differential architecture and pin-strapped configuration capabilities provided by this specific model.

Part Context

This component belongs to the LTC6601 family of active filters and drivers. It is designed to replace discrete RC filter networks and external amplifiers, reducing board space and component count while maintaining consistent and repeatable filter characteristics through internal trimming.

Replacement Considerations

The LTC6601-1 is a pin-compatible alternative within the same family, offering different trade-offs between distortion and noise performance.
