LTC6601IUF-1#PBF

Overview

The LTC6601IUF-1#PBF 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 provides programmable gain ranging 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 × 4mm 20-lead QFN package.

Feature Summary

• Pin-configurable gain and filter response with on-chip trimmed components
• Three-state BIAS pin enabling adjustable power consumption and shutdown
• Adjustable output common mode voltage with rail-to-rail output swing
• Low noise and low distortion characteristics suitable for ADC driving

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 #PBF indicates tube packaging when sourcing. Confirm the I-grade designation ensures operation across the full industrial temperature range of –40°C to 85°C. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure authenticity and correct revision level before procurement.

Selection Notes

Select this component for applications requiring precise, pin-strapped filter configurations without external passive components. Consider the available cutoff frequency options and gain settings to match signal processing requirements. Evaluate the power consumption trade-offs between high-performance and low-power modes based on system thermal constraints.

Part Context

This part belongs to the LTC6601 family of active filters. The IUF-1 variant specifically denotes the industrial temperature grade and the 20-lead QFN package configuration. It serves as a precision signal conditioning solution within Analog Devices' portfolio of mixed-signal integrated circuits designed for high-frequency data acquisition systems.

Replacement Considerations

Consult Analog Devices for current availability status as discontinuance notifications may apply. Verify functional compatibility if substituting with other members of the LTC6601 series or alternative differential filter drivers.
