LT6604CUFF-10#PBF

Overview

The LT6604CUFF-10#PBF 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 operation with 3V, 5V, and ±5V supplies. Gain is resistor-programmable via external resistors. Key electrical parameters include an 82dB signal-to-noise ratio at unity gain with a 3V supply, 61dB common mode rejection ratio, and 40µA input bias current. It operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrates two fully differential amplifiers with fourth-order lowpass filters
• Provides adjustable output common mode voltage for ADC interfacing
• Features guaranteed phase and gain matching between channels
• Supports single-ended to differential conversion

Applications

• Dual differential ADC driver plus filter
• High-speed test and measurement equipment
• Medical imaging systems
• Wireless infrastructure antialiasing

Procurement Notes

Verify the specific suffix CUFF indicates the commercial temperature grade (0°C to 70°C) distinct from the industrial IUFF variant. Confirm package integrity upon receipt as the component utilizes a small QFN form factor. Ensure ordering documentation matches the exact part number LT6604CUFF-10#PBF to guarantee correct thermal and electrical specifications.

Selection Notes

Select this component when simultaneous filtering and differential amplification are required in a compact footprint. It is suitable for applications needing precise channel-to-channel matching. Consider the resistor-programmable gain architecture for flexible system design. Evaluate power supply requirements against the specified 3V minimum operating voltage.

Part Context

This part belongs to the LT6604 family of dual differential amplifiers with integrated lowpass filters. The 'C' designation specifies the commercial temperature range, while 'UFF' denotes the 34-lead QFN package. The '#PBF' suffix indicates lead-free finish compliance. It serves as a specialized solution for high-frequency signal conditioning tasks.

Replacement Considerations

The LT6604IUFF-10#PBF is the industrial temperature rated equivalent (-40°C to 85°C). Verify if the extended temperature range is necessary for the target application environment before substituting.
