LT6402IUD-6#PBF

Overview

The LT6402IUD-6#PBF 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. The component is housed in a compact 16-lead 3mm × 3mm QFN package.

Feature Summary

• Integrated 75MHz differential low-pass filter for reduced external component count
• Adjustable output common mode voltage eliminating need for output transformers
• Low input-referred noise and high linearity suitable for driving high-speed ADCs
• Minimal support circuitry requirements for both input and output stages

Applications

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

Procurement Notes

Verify the 'I' suffix indicates industrial temperature range (-40°C to 85°C) performance guarantees. Confirm the '#PBF' designation corresponds to lead-free packaging and RoHS compliance. Ensure the specific part number matches the required fixed 6dB gain configuration within the LT6402 family.

Selection Notes

Select this variant when a fixed 6dB gain is required for signal conditioning. Consider the internal 75MHz filter if anti-aliasing is needed without additional components. Verify that the 5V single-supply operation aligns with system power constraints. Check input impedance matching requirements against the 200Ω differential input specification.

Part Context

This component belongs to the LT6402 family of differential amplifiers designed for high-speed data acquisition. The family offers various gain options including unity, two, and four, alongside the six-decibel version. These devices are engineered for ease of use in RF and IF applications requiring precise differential drive capabilities.

Replacement Considerations

LT6402CUD-6#PBF: Commercial grade equivalent with identical electrical specifications but guaranteed performance from 0°C to 70°C.
