LT6402IUD-6#TRPBF

Overview

The LT6402IUD-6#TRPBF is a low distortion, low noise differential amplifier and ADC driver with a fixed gain of 6dB. It features a 300MHz -3dB bandwidth and operates on a single 5V supply consuming 30mA. The device includes built-in 75MHz differential low-pass filtering at the +OUTFILTERED and –OUTFILTERED pins. It provides adjustable output common mode voltage via the VOCM pin and supports DC or AC-coupled operation within a –40°C to 85°C temperature range.

Feature Summary

• Integrated 75MHz differential low-pass filter for simplified anti-aliasing
• Adjustable output common mode voltage eliminates external transformers
• Low input-referred noise density for high signal integrity
• Minimal support circuitry requirements for direct ADC interfacing

Applications

• Differential ADC driver for imaging and communications systems
• IF sampling receivers and SAW filter interfacing
• Single-ended to differential conversion
• General-purpose differential gain block

Procurement Notes

Verify the specific 'I' grade designation ensures guaranteed performance across the full industrial temperature range of –40°C to 85°C. Confirm the '#TRPBF' suffix indicates tape and reel packaging compatible with automated assembly processes. Ensure compatibility with the 16-lead QFN footprint during procurement planning.

Selection Notes

Select this component when a fixed 6dB gain is required for driving high-speed ADCs directly. The integrated filtering reduces external component count compared to unfiltered variants. Consider the 'I' grade for applications requiring guaranteed specifications over the full industrial temperature range rather than the commercial grade.

Part Context

This part belongs to the LT6402-6 series, which offers a fixed 6dB gain configuration. It is designed specifically for ease of use in communications transceiver applications. The series provides options for different temperature grades and packaging formats while maintaining consistent electrical characteristics for differential signal processing.

Replacement Considerations

LT6402CUD-6#TRPBF serves as a functional substitute with identical electrical specifications but a commercial temperature range.
