LT6604CUFF-10#TRPBF

Overview

The LT6604CUFF-10#TRPBF is a dual very low noise differential amplifier and 10MHz lowpass filter. It integrates two matched, fully differential amplifiers, each with a fourth-order lowpass filter approximating a Chebyshev response. The device operates on a single 3V supply or ±5V supplies. It features resistor-programmable differential gain, adjustable output common mode voltage, and guaranteed phase and gain matching between channels.

Feature Summary

• Integrates two matched, fully differential amplifiers with fourth-order lowpass filters
• Provides adjustable output common mode voltage for direct ADC interfacing
• Features highly matched gain and phase between the two channels
• Enables level shifting of differential signals to accommodate reference voltage requirements

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 TRPBF indicates tape and reel packaging when sourcing this component. Confirm the C grade temperature range meets application requirements, as it is specified for 0°C to 70°C operation. Ensure the 34-lead QFN package dimensions align with the PCB footprint design. Cross-reference the manufacturer part number to avoid confusion with other temperature grades or package styles.

Selection Notes

Select this component when a dual-channel solution with integrated filtering is required to minimize board space and component count. The fixed 10MHz cutoff frequency suits applications needing precise band-limiting without external filter tuning. Consider the input bias current and offset voltage specifications if processing small differential signals. Verify that the available gain setting resistors provide the necessary passband gain for the system signal chain.

Part Context

This part belongs to the LT6604 family of dual differential amplifiers with integrated lowpass filters. It shares architectural similarities with single-channel variants like the LT6600 but offers dual functionality in one package. The device is designed to replace discrete amplifier and filter combinations, reducing distortion and noise while simplifying the interface to high-speed analog-to-digital converters.
