LT6402IUD-20#TRPBF

Overview

The LT6402IUD-20#TRPBF is a low distortion, low noise differential amplifier and ADC driver designed for applications from DC to 300MHz. It features a fixed gain of 20dB (10V/V) and operates on a single 5V supply with a typical current consumption of 30mA. The device includes both unfiltered outputs (+OUT, –OUT) and built-in filtered outputs (+OUTFILTERED, –OUTFILTERED) with a 75MHz -3dB bandwidth. It provides adjustable output common mode voltage via the VOCM pin, eliminating the need for external transformers or AC-coupling capacitors in many configurations.

Feature Summary

• Integrated differential low-pass filter at the +OUTFILTERED and –OUTFILTERED pins
• Adjustable output common mode voltage control via the VOCM pin
• Supports both DC-coupled and AC-coupled input operation
• Capable of single-ended to differential and differential to single-ended conversion

Applications

• Differential ADC driver for high-speed data acquisition systems
• IF sampling receivers
• SAW filter interfacing and buffering
• Level shifting circuits

Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the temperature grade 'I' indicates an operating range of –40°C to 85°C. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability, as counterfeit components may exhibit degraded RF performance or incorrect electrical characteristics.

Selection Notes

Select this component when a fixed 20dB gain is required for driving high-resolution ADCs without external feedback resistors. Choose the filtered outputs if anti-aliasing filtering near 75MHz is needed to simplify the PCB layout. Consider the unfiltered outputs if a wider bandwidth up to 300MHz is necessary for specific wideband signal processing applications.

Part Context

This part belongs to the LT6402 family of differential amplifiers manufactured by Analog Devices Inc. The 'I' designation specifies the industrial temperature grade, while the 'UD' package code identifies the 16-lead 3mm x 3mm QFN form factor. The '#TRPBF' suffix denotes the lead-free tape and reel shipping configuration.

Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers before implementation.
