LTC6404CUD-4#TRPBF

Overview

The LTC6404CUD-4#TRPBF is a 600MHz, low noise, high precision fully differential input/output amplifier optimized for single-supply operation. It features a closed-loop gain of 4V/V and a slew rate of 1200V/μs. The device operates on supply voltages from 2.7V to 5.25V with a typical supply current of 30.2mA. It includes an adjustable output common mode voltage, rail-to-rail output swing, and a built-in 88.5MHz differential lowpass filter.

Feature Summary

• Fully differential input and output architecture
• Built-in 88.5MHz differential single-pole lowpass filter
• Hardware shutdown feature for low power consumption
• Adjustable output common mode voltage

Applications

• Differential Input A/D Converter Driver
• Single-Ended to Differential Conversion/Amplification
• Common Mode Level Translation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the C grade temperature range meets application requirements. Check for lead-free finish compliance if required by manufacturing standards. Ensure the QFN package footprint matches the PCB layout design.

Selection Notes

Select this variant for applications requiring a fixed closed-loop gain of 4V/V. Consider the 600MHz bandwidth and 1200V/μs slew rate for high-speed signal processing. Evaluate the 1.5nV/√Hz input noise density for low noise system designs. Verify compatibility with 16-bit or 18-bit ADCs driving requirements.

Part Context

This component belongs to the LTC6404 family of AC precision amplifiers. Other variants include the LTC6404-1 (unity-gain) and LTC6404-2 (gain ≥2V/V). All share the same compact 3mm × 3mm QFN package and core performance characteristics, differing primarily in internal feedback networks for stability at specific gains.

Replacement Considerations

LTC6404IUD-4#TRPBF offers the same electrical specifications but with an extended industrial temperature range of –40°C to 85°C compared to the commercial grade.
