LTC6404IUD-2#TRPBF

Overview

The LTC6404IUD-2#TRPBF is a high-speed, low-noise, fully differential input/output amplifier and driver from Analog Devices. Designed for single-supply operation between 2.7V and 5.25V, it features a closed-loop bandwidth extending to 600MHz and a slew rate of 700V/μs. The device incorporates an integrated 88.5MHz differential single-pole lowpass filter with dedicated filtered outputs (OUTF+, OUTF–). It provides rail-to-rail output swing, adjustable output common mode voltage, and hardware shutdown functionality that reduces supply current to approximately 250μA.

Feature Summary

• Fully differential architecture supporting both differential and single-ended inputs with common mode level shifting capabilities
• Integrated 88.5MHz differential single-pole lowpass filter providing additional filtered output pins
• Hardware shutdown feature significantly reducing power consumption during inactive periods
• Rail-to-rail output swing with adjustable output common mode voltage control

Applications

• Differential input to analog-to-digital converter (ADC) driving
• Single-ended to differential conversion and amplification
• Common mode level translation in signal processing chains

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'I' grade designation matches the required industrial temperature range of –40°C to 85°C for your application environment. Ensure compatibility with the 16-lead QFN package footprint during PCB layout review.

Selection Notes

Select this variant over the -1 or -4 models if a closed-loop gain greater than or equal to 2V/V is required. The -2 configuration offers higher slew rates compared to the unity-gain stable -1 version while maintaining the same low noise profile suitable for precision data acquisition systems.

Part Context

This component belongs to the LTC6404 family of AC precision amplifiers optimized for 3V single-supply operation. The family includes variants designed for different closed-loop gains (-1, -2, -4), all sharing the same compact 3mm × 3mm × 0.75mm 16-pin leadless QFN package and core performance characteristics like low noise and high linearity.

Replacement Considerations
