LTC6403HUD-1#TRPBF

Overview

The LTC6403HUD-1#TRPBF is a precision, low noise, low distortion fully differential input/output amplifier optimized for 3V to 5V single supply operation. It features a 200MHz gain-bandwidth product and 2.8nV/√Hz input-referred voltage noise. The device includes unfiltered outputs (+OUT, –OUT) and filtered outputs (+OUTF, –OUTF) with a built-in 44.2MHz differential single-pole lowpass filter. It operates on supplies from 2.7V to 5.25V, draws 10.8mA typical supply current, and supports hardware shutdown reducing consumption to 170µA. It is housed in a 3mm × 3mm 16-pin QFN package.

Feature Summary

• Fully differential input and output architecture with rail-to-rail output swing
• Built-in clamp mechanism enabling fast overdrive recovery
• Adjustable output common mode voltage via the VOCM pin
• Low power hardware shutdown capability

Applications

• Differential input A/D converter driver
• Single-ended to differential conversion and amplification
• Common mode level translation
• Low voltage, low noise signal processing

Procurement Notes

Verify that the specific suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the H temperature grade designation aligns with the intended operating environment of –40°C to 125°C. Ensure the ordering information matches the exact lead-free finish specifications provided in the manufacturer's documentation.

Selection Notes

Select this component when driving high-resolution ADCs requiring low noise and wide bandwidth. The adjustable output common mode voltage allows flexibility in interfacing with various downstream components. Consider the internal filtering options if bandwidth limitation to 44.2MHz is acceptable for the application requirements.

Part Context

This part belongs to the LTC6403-1 family of fully differential amplifiers. The HUD-1 suffix indicates an industrial/high-temperature grade variant packaged in a 16-lead QFN. It shares functional characteristics with other members of the series but is distinguished by its extended temperature range and specific packaging configuration.
