LTC6601IUF-1#TRPBF

Overview

The LTC6601IUF-1#TRPBF is a fully differential second-order active 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 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 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 control for 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 ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the I-grade designation corresponds to the specified industrial temperature range requirements for your application environment. Ensure compatibility with the required QFN footprint during procurement planning.

Selection Notes

Select this component when a fully differential active filter with minimal external components is required. Consider the pin-configurable cutoff frequency options between 5MHz and 28MHz to match signal bandwidth needs. Evaluate the BIAS pin configuration to optimize power consumption versus performance based on system thermal constraints.

Part Context

This part belongs to the LTC6601 family of low-noise active filters. The IUF-1 variant specifically denotes the industrial temperature grade (-40°C to 85°C) and the 20-lead QFN package. The #TRPBF suffix identifies the tape and reel packaging format with lead-free finish, distinguishing it from tube-packaged equivalents.
