LTC6403CUD-1#TRPBF

Overview

The LTC6403CUD-1#TRPBF is a precision, low noise, fully differential input/output amplifier optimized for single supply operation between 2.7V and 5.25V. It features a 200MHz gain-bandwidth product, 2.8nV/√Hz input-referred voltage noise density, and 60mA output current capability. The device includes unfiltered outputs (+OUT, –OUT) and integrated filtered outputs (+OUTF, –OUTF) with a 44.2MHz -3dB bandwidth. It operates within a commercial temperature range of 0°C to 70°C and is housed in a compact 3mm × 3mm 16-lead QFN package.

Feature Summary

• Fully differential architecture providing rail-to-rail output swing and even-order harmonic distortion cancellation
• Integrated passive lowpass filter on +OUTF and –OUTF pins for bandlimited signal processing
• Hardware shutdown feature enabling significant power reduction when inactive
• Adjustable output common mode voltage via the VOCM pin for flexible level shifting

Applications

• Driving differential input analog-to-digital converters (ADCs)
• Single-ended to differential conversion with common mode level shifting
• Low voltage, low noise signal processing circuits

Procurement Notes

Verify that the specific suffix #TRPBF corresponds to tape and reel packaging rather than tube packaging. Confirm the C grade designation aligns with the required 0°C to 70°C operating temperature range for your application environment. Ensure compatibility with the 16-lead QFN footprint during procurement planning.

Selection Notes

Select this component when driving high-resolution ADCs requiring low noise and wide bandwidth. Consider the integrated filter if system-level filtering is desired without external components. Verify that the 2.7V minimum supply voltage meets the system's power constraints and that the 60mA drive capability satisfies the load requirements.

Part Context

This part belongs to the LTC6403-1 family of fully differential amplifiers. The 'C' suffix indicates the commercial temperature grade (0°C to 70°C), distinguishing it from the I (–40°C to 85°C) and H (–40°C to 125°C) grades. The '#TRPBF' suffix specifies the tape and reel packaging format for automated assembly.
