LT6604IUFF-10#TRPBF

Overview

The LT6604IUFF-10#TRPBF is a dual very low noise differential amplifier and 10MHz lowpass filter. It integrates two matched channels, each featuring a fourth-order Chebyshev response filter. The device supports 3V, 5V, and ±5V supplies with an operating temperature range of –40°C to 85°C. Key electrical parameters include a gain bandwidth product of 10MHz, common mode rejection ratio of 61dB, input bias current of 40µA, and power supply current of 35mA per channel at 3V. It utilizes a 34-lead QFN package.

Feature Summary

• Provides guaranteed phase and gain matching between channels
• Features resistor-programmable differential gain for flexible signal processing
• Includes adjustable output common mode voltage for direct ADC interfacing

Applications

• Dual differential ADC driver plus filter
• Single-ended to differential converter
• Matched dual differential filter stage
• High speed test and measurement equipment
• Medical imaging systems

Procurement Notes

Verify the specific suffix IUFF-10#TRPBF against official Analog Devices documentation to confirm industrial temperature grade and tape-and-reel packaging. Ensure compatibility with the 34-lead QFN footprint during procurement planning. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing orders.

Selection Notes

Select this component when designing circuits requiring integrated filtering and amplification in a compact form factor. The industrial temperature rating makes it suitable for harsh environments. Consider the 34-lead QFN package constraints and thermal dissipation requirements. Verify that the 10MHz cutoff frequency aligns with system bandwidth needs and that the differential architecture matches the signal source characteristics.

Part Context

This part belongs to the LT6604 family of dual differential amplifiers with integrated lowpass filters. The 'I' designation indicates an extended industrial temperature range compared to commercial variants. The '#TRPBF' suffix specifies tape-and-reel packaging with lead-free finish. This series is designed for high-speed data acquisition and signal conditioning applications requiring precise channel matching.

Replacement Considerations

Consult Analog Devices marketing for parts specified with wider operating temperature ranges. Review the datasheet back page for related single and dual differential amplifiers with integrated 2.5MHz to 20MHz lowpass filters to identify potential functional equivalents within the same product family.
