LT6604CUFF-5#TRPBF

Overview

The LT6604CUFF-5#TRPBF is a dual-channel integrated circuit featuring very low noise differential amplifiers and 5MHz fourth-order lowpass filters. It provides matched gain and phase characteristics with resistor-programmable differential gain. The device supports single 3V, 5V, or ±5V supplies and includes adjustable output common mode voltage for direct ADC interfacing. Packaged in a 34-lead QFN, it offers high channel separation and low distortion suitable for precision signal processing.

Feature Summary

• Integrates two fully differential amplifiers with 4th order 5MHz lowpass filters
• Provides guaranteed gain and phase matching between channels
• Features adjustable output common mode voltage for level shifting
• Supports single-ended to differential conversion capabilities

Applications

• Dual differential ADC driver and filter applications
• Single-ended to differential converter circuits
• High-speed test and measurement equipment
• Medical imaging systems
• Wireless infrastructure and networking applications

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 34-lead QFN footprint during PCB layout planning.

Selection Notes

Select this component for applications requiring simultaneous filtering and amplification with minimal external components. Consider the resistor-programmable gain feature for flexible system design. Evaluate the power supply requirements against the specified 3V to 11V operating range. Assess the thermal performance within the QFN package constraints for the intended environment.

Part Context

This part belongs to the LT6604 family of dual differential amplifiers with integrated lowpass filters. Variants exist with different cutoff frequencies such as 2.5MHz and 15MHz. The C grade denotes commercial temperature operation, while the I grade covers extended industrial ranges. All variants share the same 34-lead QFN package and functional architecture.

Replacement Considerations

LT6604IUFF-5#TRPBF serves as a verified substitute offering identical electrical specifications but with an extended operating temperature range from -40°C to 85°C compared to the commercial grade.
